    Influence of ear canal occlusion and static pressure difference on bone conduction thresholds: Implications for mechanisms of bone conduction2005In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 44, no 5, p. 302-306Article in journal (Refereed)
    Abstract [en]

    The effect of air pressure change on bone conduction (BC) hearing thresholds in the occluded ear was investigated. The pump manometer system of an impedance bridge was used to change the air pressure in the ear canal of twenty-two normally hearing subjects. BC thresholds were measured with: (1) open ear; (2) the ear canal occluded with a probe tube and application of 0 daPa air pressure; and (3) the ear canal occluded with a probe tube and application of -350 daPa air pressure. Thresholds were lower in condition 2 than in condition 1, the difference decreasing from 27 dB at 2500 Hz to 4.5 dB at 2000 Hz. Thresholds were higher in condition 3 than in condition 2. The results are interpreted in terms of changes in the relative contribution of the three routes of transmission for BC sound produced by occlusion and by a static pressure difference.

    International Collegium of Rehabilitative Audiology (ICRA) recommendations for the construction of multilingual speech tests ICRA Working Group on Multilingual Speech Tests2015In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 54, p. 17-22Article in journal (Refereed)
    Abstract [en]

    Objective: To provide guidelines for the development of two types of closed-set speech-perception tests that can be applied and interpreted in the same way across languages. The guidelines cover the digit triplet and the matrix sentence tests that are most commonly used to test speech recognition in noise. They were developed by a working group on Multilingual Speech Tests of the International Collegium of Rehabilitative Audiology (ICRA). Design: The recommendations are based on reviews of existing evaluations of the digit triplet and matrix tests as well as on the research experience of members of the ICRA Working Group. They represent the results of a consensus process. Results: The resulting recommendations deal with: Test design and word selection; Talker characteristics; Audio recording and stimulus preparation; Masking noise; Test administration; and Test validation. Conclusions: By following these guidelines for the development of any new test of this kind, clinicians and researchers working in any language will be able to perform tests whose results can be compared and combined in cross-language studies.

    Audiometric screening of a population with intellectual disability2013In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 52, no 1, p. 50-56Article in journal (Refereed)
    Abstract [en]

    Objective: Evaluation of pure-tone audiometry (PTA) in hearing screening of a population with mild to profound intellectual disability (ID).

    Design: PTA was performed at six frequencies at the screening level 20 dB HL. Referral criteria were threshold levels ≥ 25 dB HL at two or more frequencies for one ear or both.

    Study sample: 1478 participants aged 7–91 years were included.

    Results: 1470 (99.5%) people cooperated in screening of which 1325 (90%) could be tested on both ears at all six frequencies. A majority, 987 (66.8%), performed ordinary PTA, 234 (15.8%) conditioned play audiometry, and 249 (16.9%) behavioural observation audiometry. Six hundred and sixty-nine (45%) passed and 809 (55%) failed according to referral criteria. Of those failing, 441 (54.5%) accepted referral to clinical evaluation.

    Conclusions: PTA with slight modifications is applicable for screening of a population with mild to profound intellectual disability. The most challenging and time-consuming activity is to introduce the test procedure in a way that reduces anxiety and establishes trust.

    Treatment of tinnitus in the elderly: A controlled trial of cognitive behavior therapy2005In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 44, no 11, p. 671-675Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to investigate the effects of cognitive behavioral therapy (CBT) in elderly people with tinnitus (<65 years). Thirty-seven patients were called in for a structured interview. Following exclusion, twenty-three participated in the trial. All participants underwent medical ear, nose, and throat (ENT) examination, audiometry, and tinnitus matchings. A randomized controlled design with a waiting list control group was used. A CBT treatment package was delivered in six weekly two hour group sessions. Outcome was measured using validated self-report inventories and daily diary ratings of annoyance, loudness and sleep quality for one week pre-treatment, post-treatment. A three month follow-up was included at which time all participants had received treatment, but in a shorter format for the control group. Results showed statistically significant reductions of tinnitus-related distress. Thus, CBT was better than no treatment, but the particular aspects of CBT that contributed to the effects can not be established. In conclusion, the findings give some support for the use of group CBT for elderly people with tinnitus. © 2005 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society.

    Understanding tinnitus distress: Introducing the concepts of moderators and mediators2008In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 47, no S2, p. S106-S111Article in journal (Refereed)
    Abstract [en]

    We focus this theoretical paper on a neglected distinction in tinnitus research between moderators and mediators of tinnitus distress. A moderator variable is one that influences the strength of a relationship between two other variables. In the paper we propose that several variables might act as moderators of tinnitus distress. Degree of hearing loss, arousal, insomnia, characteristics of tinnitus, noise sensitivity, and a range of psychological factors such as personality and perceived control are discussed as potential moderators. We then move on to mediator variables. A mediator variable is one that explains the relationship between the two other variables, and must by definition be caused by a predictor, and then mediate between the predictor and the dependent variable. We propose that stress levels (caused by tinnitus), classical conditioning, selective attention towards tinnitus, and psychological acceptance of tinnitus (versus experiential avoidance) might be mediators of distress. We encourage more research on moderators and mediators of tinnitus distress, as these will help illuminate treatment protocols and how they might work.

    A survey of public health policy on bilateral fittings and comparison with market trends: The evidence-base required to frame policy2006In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 45, no SUPPL. 1Article in journal (Refereed)
    Abstract [en]

    This report presents a review of the situation in a number of countries with respect to public health policy for funding of hearing aid services in general and support to bilateral fittings in particular. The data show considerable variations among the countries studied in number of hearing aids fitted per 1000 inhabitants, differing by a factor of 6 between the extremes. Also the percentage of bilateral fittings differs with an average estimated to be of the order of 50%. For hearing-impaired children, bilateral fittings are given full financial support in most countries studied. The data presented indicate the need for a reliable, scientifically valid evidence-base regarding bilateral hearing aid fitting. © 2006 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society.

    Negative consequences of uncorrected hearing loss - A review2003In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 42, no SUPPL. 2Article in journal (Refereed)
    Abstract [en]

    Hearing loss gives rise to a number of disabilities. Problems in recognizing speech, especially in difficult environments, give rise to the largest number of complaints. Other kinds of disabilities may concern the reduced ability to detect, identify and localize sounds quickly and reliably. Such sounds may be warning or alarm signals, as well as music and birds singing. The communicative disability affects both hearing-impaired people and other people in their environment-family members, fellow workers, etc. Hearing-impaired people are not always aware of all the consequences of the impairment, they do not always know what they are missing. Several studies have shown that uncorrected hearing loss gives rise to poorer quality of life, related to isolation, reduced social activity, and a feeling of being excluded, leading to an increased prevalence of symptoms of depression. These findings indicate the importance of early identification of hearing loss and offers of rehabilitative support, where the fitting of hearing aids is usually an important component. Several studies also point to a significant correlation between hearing loss and loss of cognitive functions. Most of these studies show such a correlation without being able to show whether the hearing loss caused the reduction in cognitive performance or if both the hearing loss and the cognitive decline are parts of a common, general age-related degeneration. A couple of these studies, however, indicate that the uncorrected hearing loss may be the cause of cognitive decline. Whichever alternative is true, the correlation should be seen as a clear indication for early hearing aid fitting for those needing it. Monaural hearing aid fitting in subjects with bilateral hearing loss may give rise to a reduced ability to recognize speech presented to the unaided ear, the so-called late-onset auditory deprivation effect. This functional decline is reversible in some but not all subjects after fitting of a hearing aid also on the previously unaided ear.

    A longitudinal study of the bilateral benefit in children with bilateral cochlear implants2015In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 54, no 2, p. 77-88Article in journal (Refereed)
    Abstract [en]

    Objective: To study the development of the bilateral benefit in children using bilateral cochlear implants by measurements of speech recognition and sound localization. Design: Bilateral and unilateral speech recognition in quiet, in multi-source noise, and horizontal sound localization was measured at three occasions during a two-year period, without controlling for age or implant experience. Longitudinal and cross-sectional analyses were performed. Results were compared to cross-sectional data from children with normal hearing. Study sample: Seventy-eight children aged 5.1-11.9 years, with a mean bilateral cochlear implant experience of 3.3 years and a mean age of 7.8 years, at inclusion in the study. Thirty children with normal hearing aged 4.8-9.0 years provided normative data. Results: For children with cochlear implants, bilateral and unilateral speech recognition in quiet was comparable whereas a bilateral benefit for speech recognition in noise and sound localization was found at all three test occasions. Absolute performance was lower than in children with normal hearing. Early bilateral implantation facilitated sound localization. Conclusions: A bilateral benefit for speech recognition in noise and sound localization continues to exist over time for children with bilateral cochlear implants, but no relative improvement is found after three years of bilateral cochlear implant experience.

    Bilateral versus unilateral cochlear implants in children: Speech recognition, sound localization, and parental reports2012In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 51, no 11, p. 817-832Article in journal (Refereed)
    Abstract [en]

    Objective: To compare bilateral and unilateral speech recognition in quiet and in multi-source noise, and horizontal sound localization of low and high frequency sounds in children with bilateral cochlear implants. Design: Bilateral performance was compared to performance of the implanted side with the best monaural speech recognition in quiet result. Parental reports were collected in a questionnaire. Results from the CI children were compared to binaural and monaural performance of normal-hearing peers. Study sample: Sixty-four children aged 5.1-11.9 years who were daily users of bilateral cochlear implants. Thirty normal-hearing children aged 4.8-9.0 years were recruited as controls. Results and Conclusions : Group data showed a statistically significant bilateral speech recognition and sound localization benefit, both behaviorally and in parental reports. The bilateral speech recognition benefit was smaller in quiet than in noise. The majority of subjects localized high and low frequency sounds significantly better than chance using bilateral implants, while localization accuracy was close to chance using unilateral implants. Binaural normal-hearing performance was better than bilateral performance in implanted children across tests, while bilaterally implanted children showed better localization than normal-hearing children under acute monaural conditions.

    Appearances are deceptive?: Long-term cognitive and central auditory sequelae from closed head injury2005In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 44, no 1, p. 39-49Article in journal (Refereed)
    Abstract [en]

    The purpose of the present study was to examine possible signs of long-term cognitive and/or central auditory sequelae seven to eleven years after a closed head injury (CHI) of sufficient severity to cause scull fracture and/or brain contusion. Another purpose was that this investigation should be carried out in a group of recovered trauma victims with, to the individual, no known or minimal sequelae. A computer-based set of five cognitive tests and three central auditory tests were used in a group of formerly brain-injured patients who considered themselves as well recovered. Most of the participants did not report any signs of cognitive or auditory impairment. Tests of working memory capacity, verbal information processing speed, phonological processing and verbal inference-making ability were used. Auditory brain response (ABR), distorted speech audiometry (interrupted speech), and phase audiometry were used to test central auditory function. The initial severity of brain damage, i.e. status when the patient arrived at the emergency ward, was estimated with Swedish Reaction Level Scale (RLS). Cognitive shortcomings after CHI were demonstrated in a high percentage (59%, 13/22) of the cases seven to eleven years after the injury. Central auditory processing disorders (APD) were also demonstrated in a fairly high percentage (58%, 11/19) of the subjects. None of the correlations between RLS and the results on cognitive and central auditory tests reached statistical significance. However, there was a correlation between cognitive performance and the results on the central auditory tests used in this investigation. Eighty percent (8/10) of those participants with pathologies on ABR and/or phase audiometry and/or IS also failed on one or more of the cognitive tasks, compared to 44% (4/9) among those with no signs of APD. It is possible, many years after CHI, to observe cognitive shortcomings and APD in a relatively high percentage of CHI cases that are subjectively considered to be fairly well recovered. The cognitive tasks used in the study have proved to be a sensitive method to discover cognitive impairments. Long-term cognitive sequelae and APD could not be predicted from RLS scores.

    Process evaluation of Internet-based cognitive behavioural therapy for adults with tinnitus in the context of a randomised control trial2018In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 57, no 2, p. 98-109Article in journal (Refereed)
    Abstract [en]

    Objective: The research objective was to identify processes that could either facilitate or hinder clinical implementation of an Internet-based cognitive behavioural therapy intervention for tinnitus in the UK. This was done by exploring the research context, the intervention components and the factors that contributed to the outcomes obtained. Design: This study investigated eight processes including the recruitment strategies, reach, research context, treatment dose delivered and received, implementation fidelity, barriers to implementation and effectiveness of the intervention. Study sample: Of the 169 registered participants, 146 were randomly assigned to the experimental or control groups (23 were excluded). The mean age was 55.57 years with an average tinnitus duration of 11.63 years. Results: The intended sample of people with distressing tinnitus who were underserved with evidence-based tinnitus interventions was reached. The full guided intervention was delivered. The recommended modules were read more than the optional modules. Intervention components such as the easily readable format and the benefits of the applied relaxation programme facilitated significant positive post-intervention outcomes. Barriers hampering the intervention application included time pressures and low self-motivation. Conclusions: Results of this process evaluation together with the outcome data can be used to facilitate translating this research into clinical practice.

    Participants experiences of an Internet-based cognitive behavioural therapy intervention for tinnitus2018In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 57, no 12, p. 947-954Article in journal (Refereed)
    Abstract [en]

    Objective: This study aimed to explore participants experiences after undertaking an Internet-based cognitive behavioural therapy intervention (ICBT) for tinnitus. Design: Semi-structured telephone interviews were conducted 6-8 months after participants undertook the ICBT intervention. Qualitative thematic analysis was used to interpret the interview data. Study sample: A purposeful sampling strategy was used to identify a diverse range of participants. Semi-structured interviews were carried out with 15 participants. The mean age was 58.5 years, 7 men and 8 women participated. Results: The analysis generated the following main themes: (1) expectations and motivation for doing the intervention, (2) experiences of the intervention, (3) intervention engagement and (4) intervention effects. Most participants expectations were hopeful that the intervention would lessen the impact of their tinnitus. Aspects of the intervention that were beneficial, as well as difficult, were identified together with the impact they had on engagement. Intervention effects were evident on both tinnitus and activities of daily life. Conclusions: The benefits described by participants indicate the potential of ICBT as an alternate form of intervention delivery. The difficulties that hampered engagement need to be addressed to enhance the application and to optimise the clinical acceptability of ICBT for tinnitus.

    Danish Reading Span data from 283 hearing-aid users, including a sub-group analysis of their relationship to speech-in-noise performance2016In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 55, no 4, p. 254-261Article in journal (Refereed)
    Abstract [en]

    Objective: This study provides descriptive statistics of the Danish reading span (RS) test for hearing-impaired adults. The combined effect of hearing loss, RS score, and age on speech-in-noise performance in different spatial settings was evaluated in a subset of participants. Design: Data from published and unpublished studies were re-analysed. Data regarding speech-in-noise performance with co-located or spatially separated sound sources were available for a subset of participants. Study sample: RS scores from 283 hearing-impaired participants were extracted from past studies, and 239 of these participants had completed a speech-in-noise test. Results: RS scores (mean = 41.91%, standard deviation = 11.29%) were related to age (p <0.01), but not pure-tone average (PTA) (p = 0.29). Speech-in-noise performance for co-located sound sources was related to PTA and RS score (both p < 0.01, adjusted R-squared = 0.226). Performance for spatially separated sounds was related to PTA (p < 0.01, adjusted R-squared = 0.10) but not RS score (p = 0.484). We found no differences between the standardized coefficients of the two regression models. Conclusions: The distribution of RS scores indicated a high test difficulty. We found that age should be controlled when RS scores are compared across populations. The experimental setup of the speech-in-noise test may influence the relationship between performance and RS score.

    New perspectives on counselling in audiological habilitation/rehabilitation2015In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 54, no 1, p. 11-19Article in journal (Refereed)
    Abstract [en]

    Objective: To develop and apply a pedagogical method focusing on Empowerment, Empathy, Competence, and Counselling: the EC programme, and to present an initial evaluation. Design: The EC programme was gradually developed within a study circle framework and in dialogue with study circle leaders and participants (clients) with hearing impairment (HI). An evaluation was carried out with the study circle leaders. Study sample : Seventeen upper secondary school students with HI took part in the development of the programme. Eighteen study circle leaders responded to a questionnaire. Results: The EC programme developed consisted of films, CD, and DVD productions to increase insight into one's own hearing ability, to demonstrate for others what HI means, strategies to evaluate situations, and help to act constructively in social situations. The study circle leaders found most of the course material appropriate and easy to use, as a whole or in parts. The leaders' evaluations indicated that the clients had increased their knowledge about how the HI affected themselves and others. The clients had improved their self-confidence and their empathic view of others. Conclusion: The EC programme can be used in its entirety or in part. Participation may lead to increased empowerment, empathy, competence and counselling ability.

    Behavioural awareness, interaction and counselling education in audiological rehabilitation: development of methods and application in a pilot study2002In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 41, no 5, p. 308-320Article in journal (Refereed)
    Abstract [en]

    In conventional audiological rehabilitation, the hearing therapist interacts with the hearing-impaired person and with significant others. In order to strengthen the personality and self-confidence of the hearing-impaired individual, a different strategy was designed and implemented whereby the pedagogic interaction was directed only towards the hearing-impaired individual, who in turn worked as a tutor/aid/counsellor to the communication partner. On the basis of an interactive communication model, new methods for rehabilitation of subjects with moderate hearing impairment were developed and evaluated in a pilot study on 13 men with noise-induced hearing loss. A course programme was developed with three main active components: (1) increased insight and knowledge; (2) education as counsellors with the ability to focus on the problems of the communication partner; and (3) motivation to change through group discussion and reflexive conversation. Increased insight and knowledge were obtained through test and training experiences in a sound environmental chamber, tutorials and discussions. The pedagogic training focused on helping the hearing-impaired subjects to become able communication counsellors in relation to their interlocutors. An act-react, offensive-defensive paradigm was used in conjunction with transactional analysis. Results of the pilot study were evaluated using questionnaires, interviews and a method of dialogue analysis. The results were evaluated for the hearing-impaired and the partner and in recordings of conversations in the home environment. There were clearly positive cognitive and emotional effects seen in the inquiries and interviews. The observations from the dialogue analysis indicated only small effects, with the exception of the two individuals with the most pronounced functional impairment, for whom dialogue was improved after the course. It was concluded that these new methods could contribute new possibilities in rehabilitation programmes, emphasizing the shared responsibility for communication and the unique competence and abilities of the hearing-impaired person.

    Tinnitus and hearing loss in 15-16-year-old students: mental health symptoms, substance use, and exposure in school2008In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 47, no 11, p. 688-694Article in journal (Refereed)
    Abstract [en]

    The current study assessed the responses from a survey titled ”Life and Health – Young People 2005”, completed by 2.878 15-16 year-old adolescents in mainstream schools in the county of Örebro, Sweden. Thirty-nine percent of students with hearing loss (slight, mild, or moderate) and 6% of students with normal hearing reported tinnitus often or always during the past three months. Almost no gender difference was observed among students with normal hearing reporting tinnitus (boys 6.3%, girls 5.6%); however, a gender difference was noticed among hard-of-hearing (HH) students (boys 50%, girls 28%). Adolescents with both hearing loss and tinnitus reported considerably higher scores for mental symptoms, substance use, and school problems than other students. Anxiety in the past three months, male gender, and alcohol consumption in the past year were associated with tinnitus in HH students; irritation and anxiety in the past three months, disability, use of illicit drugs, and truancy predicted tinnitus in the normal hearing group. Consequently, students with a hearing loss and tinnitus are at high risk and should be monitored for subsequent problems.

    Psychosocial work environment among Swedish audiologists2013In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 52, no 3, p. 151-161Article in journal (Refereed)
    Abstract [en]

    Objective: The study examined the self-reported psychosocial work environment for audiologists working in three practice types (public, completely private, and private but publicly funded).

    Design: A cross-sectional e-mail survey using the demand-control-support questionnaire, a short version of the effort-reward imbalance (ERI) questionnaire, and descriptive data.

    Study sample: Five-hundred Swedish licensed audiologists.

    Results: Overall, the results indicate differences in psychosocial work environment pertaining to the practice types. These differences are small and the type explains few percent of the variability accounted in the measures of psychosocial work environment. Social support seems important for the psychosocial work environment and is considered a reward in itself. Using the demand-control model, 29% of the audiologists reported working in a high-stress psychosocial work environment. Using the ERI-ratio to estimate the imbalance between effort and reward it was shown that that 86% of the participants experienced an unfavorable work situation where the rewards do not correspond to the efforts made.

    Conclusions: The organizational framework has minor effect on self-reported psychosocial work environment for Swedish licensed audiologists. The percentage of unfavorable ERI-ratios seen in Swedish audiologists seems conspicuously high compared to other working populations in general, but also compared to other health service workers.

    Hearing thresholds, tinnitus, and headphone listening habits in nine-year-old children2016In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 55, no 10, p. 587-596Article in journal (Refereed)
    Abstract [en]

    Objective: Investigate hearing function and headphone listening habits in nine-year-old Swedish children. Design: A cross-sectional study was conducted and included otoscopy, tympanometry, pure-tone audiometry, and spontaneous otoacoustic emissions (SOAE). A questionnaire was used to evaluate headphone listening habits, tinnitus, and hyperacusis. Study sample: A total of 415 children aged nine years. Results: The prevalence of a hearing threshold20dB HL at one or several frequencies was 53%, and the hearing thresholds at 6 and 8kHz were higher than those at the low and mid frequencies. SOAEs were observed in 35% of the children, and the prevalence of tinnitus was 5.3%. No significant relationship between SOAE and tinnitus was found. Pure-tone audiometry showed poorer hearing thresholds in children with tinnitus and in children who regularly listened with headphones. Conclusion: The present study of hearing, listening habits, and tinnitus in nine-year old children is, to our knowledge, the largest study so far. The main findings were that hearing thresholds in the right ear were poorer in children who used headphones than in children not using them, which could be interpreted as headphone listening may have negative consequences to childrens hearing. Children with tinnitus showed poorer hearing thresholds compared to children without tinnitus.

    Quality of life, psychosocial consequences and audiological rehabilitation after sudden sensorineural hearing loss2011In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 50, no 2, p. 139-144Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE:

    Sudden sensorineural hearing loss (SSHL) is characterized by a rapid loss of hearing, most often of cochlear origin. Very little attention has been paid in the literature to quality of life (QoL), psychosocial consequences and audiological rehabilitation after SSHL.

    DESIGN:

    We studied how level of hearing loss, hearing recovery, tinnitus and vertigo affect QoL after SSHL and the psychosocial consequences of SSHL in terms of sick leave. Furthermore, the audiological rehabilitation given to patients in connection with SSHL and the benefit of the rehabilitation were studied.

    STUDY SAMPLE:

    Three hundred and sixty-nine (369) patients with SSHL were analysed in the present study.

    RESULTS:

    Annoying tinnitus and remaining vertigo after SSHL were the strongest predictors of negative effects on QoL.

    CONCLUSIONS:

    The study indicates that patients with SSHL require extended audiological rehabilitation including a multi-disciplinary rehabilitation approach (medical, social and psychological) to cope with the complex issues that can arise after SSHL.

    Hearing-aid use and benefit: a long-term follow-up in patients undergoing surgery for otosclerosis2013In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 52, no 3, p. 194-199Article in journal (Refereed)
    Abstract [en]

    Objectives: The aims of the study were to assess hearing-aid uptake in patients with otosclerosis 28-30 years after stapedectomy and to evaluate hearing-aid benefit to users.

    Design: A retrospective study was performed; it included a review of medical records and follow-up 28-30 years after surgery, including audiometry, clinical examination, structured interview, and a validated questionnaire, IOI-HA.

    Study sample: Sixty-five patients, who had undergone stapedectomy at a tertiary referral center in 1977-79. Results: In 95% of the subjects there was a theoretical need for hearing-aid amplification at follow-up; 46% of the subjects had no hearing aids, while 26% had unilateral and 28% bilateral hearing aids. Hearing sensitivity in the best ear predicted hearing-aid uptake. Of the subjects with a hearing aid, 94% were everyday users and 54% were full-time users (> 8 hours/day). The subjects reported a high level of satisfaction (mean 4.5) and benefit (mean 4.2), but also residual activity limitations (mean 3.1).

    Conclusions: The study shows that there is an unmet need for long-term hearing rehabilitation among patients previously undergoing surgery for otosclerosis. The patients who were using hearing aids were generally very satisfied with their hearing aids, but they still reported residual activity limitations.

    Hearing-related, health-related quality of life in patients who have undergone otosclerosis surgery: a long-term follow-up study2015In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 54, no 2, p. 63-69Article in journal (Refereed)
    Abstract [en]

    Objectives: The aims of the study were to assess health-related quality of life and hearing-related disability in subjects with otosclerosis 30 years after surgery.

    Design: An observational study was performed. Medical records were reviewed, a clinical examination as well as audiometric assessments were performed. Generic health-related quality of life was assessed by the SF-36v2 and hearing disability by a shortened version of SSQ (speech spatial and qualities of hearing scale).

    Study sample: Sixty-fi ve individuals, who had undergone stapedectomy in 1977-79 at a tertiary referral center.

    Results: Generic health-related quality of life according to SF-36 subscale scores was comparable to that of an age- and sex-matched reference population. The SF-36 mental component summary score (MCS) was, however, significantly better than that of the reference population. The mental and physical summary component scores correlated significantly to hearing disability measured by the SSQ but not to hearing impairment. Hearing disability was displayed in all SSQ sub-scores, especially in more complex listening situations and in the localization of sounds.

    Conclusions: This study shows that individuals with otosclerosis, 30 years after surgery, have a good generic health-related quality of life, despite moderate to severe hearing loss and significant hearing disabilities.

    Methodology for quantifying perceptual effects from noise suppression systems2005In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 44, no 12, p. 721-732Article in journal (Refereed)
    Abstract [en]

    Methodology is proposed for perceptual assessment of both subjective sound quality and speech recognition in such way that results can be compared between these two aspects, Validation is performed with a noise suppression system applied to hearing instruments. A method termed Interpolated Paired Comparison Rating (IPCR) was developed for time efficient assessment of subjective impression of different aspects of sound quality for a variety of noise conditions. The method is based on paired comparisons between processed and unprocessed stimuli, and the results are expressed as the difference in signal-to-noise ratio (dB) between these that give equal subjective impression. For tests of speech recognition in noise, validated adaptive test methods can be used that give results in terms of speech-to-noise ratio. The methodology was shown to be sensitive enough to detect significant mean differences between processed and unprocessed speech in noise, both regarding subjective sound quality and speech recognition ability in groups consisting of 30 subjects. An effect on sound quality from the noise suppression equivalent to about 3-4 dB is required to be statistically significant for a single subject. A corresponding effect of 3-6 dB is required for speech recognition (one-sided test). The magnitude of difference that occurred in the present study for sound quality was sufficient to show significant differences for sound quality within individuals, but this was not the case for speech recognition.

    Different approaches in the assessment of audiological rehabilitation: a meta-theoretical perspective2003In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 42, no Suppl 1, p. S112-S117Article in journal (Refereed)
    Abstract [en]

    The aim of this article is to highlight some elements (e.g. the view on truth, causality, context and methods) in three different meta-theoretical approaches to assessment and to discuss their implications: external realism, critical realism, and anti-realism. Although there are many differences between external realism and anti-realism, their main shortcoming is the failure to answer one of the basic questions in assessment research: 'What works for whom in what circumstances?' In order to answer this question, one needs a deep-structure ontology and a theory including mechanisms and contexts, which one finds in critical realism. An adequate approach to an evaluation process can be described as follows. The point of departure is a theory describing how mechanisms work in context and what the expected outcomes are. Hypotheses are formulated suggesting answers to the question 'What might work for whom in what circumstances? Data are collected in order to answer the question. Different methods are used which can shed light on the phenomenon. The outcome of the evaluation process is to find the conditions under which a specific outcome is produced.

    International classification of functioning, disability, and health core sets for hearing loss: A discussion paper and invitation2010In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 49, no 4, p. 256-262Article in journal (Refereed)
    Abstract [en]

    The World Health Organization’s International Classification of Functioning, Disability and Health (ICF) has adopted a multifactorial understanding of functioning and disability, merging a biomedical paradigm with a social paradigm into a wider understanding of human functioning. Altogether there are more than 1400 ICF-categories describing different aspects of human functioning and there is a need to developing short lists of ICF categories to facilitate use of the classification scheme in clinical practice. To our knowledge, there is currently no such standard measuring instrument to facilitate a common validated way of assessing the effects of hearing loss on the lives of adults. The aim of the project is the development of an internationally accepted, evidence-based, reliable, comprehensive and valid ICF Core Sets for Hearing Loss. The processes involved in this project are described in detail and the authors invite stakeholders, clinical experts and persons with hearing loss to actively participate in the development process.

    Deafblindness, ontological security, and social recognition2008In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 47, no s2, p. s119-s123Article in journal (Refereed)
    Abstract [en]

    Trust, ontological security, and social recognition are discussed in relation to self-identity among people with acquired deafblindness. To date the phenomenon has not been elaborated in the context of deafblindness. When a person with deafblindness interacts with the social and material environment, the reliability, constancy, and predictability of his or her relations is crucial for maintaining or achieving ontological security or a general and fairly persistent feeling of well-being. When these relations fundamentally change, the impact on ontological security will be very negative. The construction of social recognition through the interaction between the self and others is embodied across three dimensions: at the individual level, at the legal systems level, and at the normative or value level. The relationship between trust and ontological security on the one hand and social recognition on the other hand is discussed. It is argued that these basic processes affecting personality development have to be identified and acknowledged in the interactions people with deafblindness experience. Some implications for the rehabilitation of people with acquired deafblindness are presented and illustrated.

    Psychosocial work environment, hearing impairment and health2004In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 43, no 7, p. 383-389Article in journal (Refereed)
    Abstract [en]

    This article summarizes results from a study of hearingimpaired men and women in the labour force in Sweden. A questionnaire about psychosocial work environment (in accordance with the Demand-Control Model), health and wellbeing was sent out and answered by 445 hearingimpaired people, 20-64 years of age. A large reference group had previously answered the same questionnaire. The results indicate that imbalances between demand and control (i.e. high demand and low control, so-called high stress work type) is more common among hearingimpaired people than in the reference group. The outcome of the combination high demand and low control among hearing-impaired people is (much) worse than among hearing-impaired people with other work types ( passive, active, low stress). Hearing-impaired people with the high-stress work type more frequently report bad physical health status and psychological wellbeing regarding a number of indicators. There is, moreover, a tendency for women to be worse off than men. Our data suggest that those involved in audiological rehabilitation should pay great attention to hearing-impaired people with jobs that can be characterized as high stress.

    Influence of stimulation position on the sensitivity for bone conduction hearing aids without skin penetration2016In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 55, no 8, p. 439-446Article in journal (Refereed)
    Abstract [en]

    Objective: This study explores the influence of stimulation position on bone conduction (BC) hearing sensitivity with a BC transducer attached using a headband. Design:(1) The cochlear promontory motion was measured in cadaver heads using laser Doppler vibrometry while seven different positions around the pinna were stimulated using a bone anchored hearing aid transducer attached using a headband. (2) The BC hearing thresholds were measured in human subjects, with the bone vibrator Radioear B71 attached to the same seven stimulation positions. Study sample: Three cadaver heads and twenty participants. Results: Stimulation on a position superior-anterior to the pinna generated the largest promontory motion and the lowest BC thresholds. Stimulations on the positions superior to the pinna, the mastoid, and posterior-inferior to the pinna showed similar magnitudes of promontory motion and similar levels of BC thresholds. Conclusion: Stimulations on the regions superior to the pinna, the mastoid, and posterior-inferior to the pinna provide stable BC transmission, and are insensitive to small changes of the stimulation position. Therefore it is reliable to use the mastoid to determine BC thresholds in clinical audiometry. However, stimulation on a position superior-anterior to the pinna provides more efficient BC transmission than stimulation on the mastoid.

    Analysis of counted behaviors in a single-subject design: Modeling of hearing-aid intervention in hearing-impaired patients with Alzheimer's disease2005In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 44, no 1, p. 31-38Article in journal (Refereed)
    Abstract [en]

    Clinical procedures related to patients with Alzheimer's Disease (AD) largely fail to address the patient's hearing. Given the challenges of this population, unconventional indicators of treatment efficacy may be required. Palmer et al (1999) reported on caregiver-tracked behaviors as outcome measures for hearing aid intervention. Using these data, hearing aid use and subsequent behavior was modeled as a first-order dynamic system, characterized by responses following an exponential time course. The results of such modeling suggest predictable outcomes of hearing aid intervention, or at least useful parameters of quantification (e.g. time-constant and steady-state response), permitting critical assessment of effects of intervention on negative behaviors versus hearing aid use, comparisons among behaviors, and/or comparisons of hearing-aid-use patterns and behavior counts among patients. Use in this and other difficult-to-test populations warrant further study to evaluate clinical efficacy of the analysis described. © 2005 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society.

    Transmission of bone-conducted sound in the human skull measured by cochlear vibrations2008In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 47, no 12, p. 761-769Article in journal (Refereed)
    Abstract [en]

    One limitation with the Bone Anchored Hearing Aid (Baha) is too poor amplification for patients with moderate to severe sensorineural hearing losses. Therefore, we investigated if bone conducted (BC) sound transmission improves when the stimulation approaches the cochlea. Also the influence from the squamosal suture on BC sound transmission was investigated. Both sides of the heads on seven human cadavers were used and vibrational stimulation was applied at eight positions on each side with a frequency range of 0.1-10 kHz. A laser Doppler vibrometer was used to measure the resulting velocity of the cochlear promontory. It was found that the velocity of the promontory increases as the stimulation position approaches the cochlea; this was especially apparent at distances within 2.5 cm from the ear canal opening and when the stimulation position was in the opened mastoid. At frequencies above 500 Hz there was on average 10 to 20 dB greater vibrational response at the cochlea when the stimulation was close to the cochlea compared with the normal Baha position. Moreover, even if there were general indications of attenuation of BC sound when passing the squamosal suture, an effect from the suture could not be conclusively determined.

    Does cognitive function predict frequency compressed speech recognition in listeners with normal hearing and normal cognition?2013In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 52, no 1, p. 14-22Article in journal (Refereed)
    Abstract [en]

    Objective:The aim was to investigate the relationship between cognitive ability and frequency compressed speech recognition in listeners with normal hearing and normal cognition. Design:Speech-in-noise recognition was measured using Institute of Electrical and Electronic Engineers sentences presented over earphones at 65 dB SPL and a range of signal-to-noise ratios. There were three conditions:unprocessed, and at frequency compression ratios of 2:1 and 3:1 (cut-off frequency, 1.6 kHz). Working memory and cognitive ability were measured using the reading span test and the trail making test, respectively. Study sample:Participants were 15 young normally-hearing adults with normal cognition. Results:There was a statistically significant reduction in mean speech recognition from around 80% when unprocessed to 40% for 2:1 compression and 30% for 3:1 compression. There was a statistically significant relationship between speech recognition and cognition for the unprocessed condition but not for the frequency-compressed conditions. Conclusions:The relationship between cognitive functioning and recognition of frequency compressed speech-in-noise was not statistically significant. The findings may have been different if the participants had been provided with training and/or time to acclimatize to the frequency-compressed conditions.

    Predictors of aided speech recognition, with and without frequency compression, in older adults.2015In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 54, no 7, p. 467-75Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The aim was to investigate whether cognitive and/or audiological measures predict aided speech recognition, both with and without frequency compression (FC).

    DESIGN: Participants wore hearing aids, with and without FC for a total of 12 weeks (six weeks in each signal processing condition, ABA design). Performance on a sentence-in-noise recognition test was assessed at the end of each six-week period. Audiological (severity of high frequency hearing loss, presence of dead regions) and cognitive (reading span and trail making test scores) measures were obtained and assessed as predictors of sentence-in-noise recognition with and without FC enabled.

    STUDY SAMPLE: Twelve experienced hearing-aid users (aged 65-84 years old) with moderate-to-severe high-frequency hearing loss took part in the study.

    RESULTS: The results suggest that both auditory and cognitive factors can be predictive of sentence-in-noise recognition with conventional amplification. However, only auditory factors were significantly correlated with the degree of benefit obtained from FC.

    CONCLUSIONS: The strongest predictor of aided speech recognition, both with and without FC, was high frequency hearing loss. Cognitive performance was also a predictor of benefit from conventional amplification, but not of additional benefit from the use of FC.

    Benefit from, and acclimatization to, frequency compression hearing aids in experienced adult hearing-aid users2015In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 54, no 1, p. 37-47Article in journal (Refereed)
    Abstract [en]

    Objective: The aim was to investigate whether frequency compression (FC) hearing aids provide additional benefit to that conferred by conventional amplification. Design: Participants wore the same hearing aid with FC enabled and disabled for six weeks (ABA design) in each condition. Speech recognition tests (in both quiet and in noise) were administered alongside two questionnaires. Performance was compared across the two signal processing conditions and at different time points. Study sample: Twelve experienced hearing-aid users (aged 65-84 years old) with moderate-to-severe high-frequency hearing loss participated in the study. Results: FC resulted in statistically significantly higher mean scores in all of the administered speech tests. Improvements over time were limited to high frequency phoneme perception. No effect of FC on self-report outcomes was observed. Conclusions: FC may lead to significant improvements in speech perception outcomes in both quiet and noise for many individuals. No participant was significantly disadvantaged by the use of FC.

    Temporal fine structure: relations to cognition and aided speech recognition2019In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186Article in journal (Refereed)
    Abstract [en]

    Objective: The aim of this study was to investigate how sensitivity to temporal fine structure (TFS) correlates with cognitive abilities and speech recognition in adult hearing aid users. Design: The cognitive tests included measures of working memory and executive function. Aided speech recognition was assessed using an adaptive sentence-in-noise recognition task, and a matrix sentence test presented in two types of noise, using three signal processing strategies. Study sample: One hundred eighty-nine adults with symmetrical sensorineural hearing loss, and at least one year of hearing aid experience. Results: After partialling out the effects of age, sensitivity to TFS correlated with the measures of executive function, but not with working memory. While TFS correlated with some of the speech recognition tasks, neither signal processing condition, difficulty, or background noise type affected the degree to which TFS correlated with performance. Conclusions: The results provide some evidence of an association between TFS and speech-in-noise recognition. That this association was not significantly affected by signal processing strategy goes against the idea that TFS sensitivity is likely to impact on the success of a particular hearing aid signal processing strategy. The results, together with previous findings, suggest a possible link between sensitivity to TFS and visuospatial processing.

    Cochlear implant effectiveness in postlingual single-sided deaf individuals: whats the point?2017In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 56, no 6, p. 417-423Article in journal (Refereed)
    Abstract [en]

    Objectives: By extending the indication criteria for cochlear implants (CI), the population of CI candidates increased in age, as well as range and type of hearing loss. This qualitative study identified factors that contributed to seek CI treatment in single-sided deaf individuals and gained insights how single-sided deafness (SSD) and hearing with a CI affect their lives. Design: An open-ended questionnaire and a standardised inventory (IOI-HA) were used. Qualitative data reflecting the reasons to seek CI treatment and the individual experiences after CI switch-on were collected. Study sample: A total of 19 postlingually deafened single-sided deaf CI users. Results: Participants use their CI daily and stated that their life satisfaction increased since CI activation. The analysis of the qualitative data revealed four core categories: sound localisation, tinnitus and noise sensitivity, fear to lose the second ear and quality of life. Conclusions: Our results show how strongly and diversely quality of hearing and quality of life is affected by acquired SSD and improved after CI activation. Our data suggest that the fear of hearing loss (HL) on the normal hearing (NH) ear is an important but so far neglected reason to seek treatment with a CI in individuals with postlingual SSD.

    The Oticon Medical Neuro Zti cochlear implant and the Neuro 2 sound processor: multicentric evaluation of outcomes in adults and children2020In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 59, no 2, p. 153-160Article in journal (Refereed)
    Abstract [en]

    Objective: This study evaluated the outcomes of the Oticon Medical Neuro Zti cochlear implant and the Neuro 2 sound processor. Design: Neuro One users were upgraded to Neuro 2. Monosyllabic word identification was evaluated in adults with Neuro One after &gt;= 5 months, with Neuro 2 at upgrade, and with Neuro 2 after 3 months. Self-reported listening ability, satisfaction, and usability were measured in adults and children. Study sample: Participants were 44 adults and 26 children. Results: Speech identification scores in quiet and noise were 58% and 45% with Neuro One and 67% and 55% with Neuro 2 after 3 months, respectively. Hearing impairment duration and number of active electrodes significantly predicted speech identification in noise with Neuro 2. Significantly higher questionnaire ratings were obtained for Neuro 2 than Neuro One regarding listening ability in complex listening situations, comfort and music, as well as nine aspects of satisfaction and usability. Conclusion: This study demonstrates the clinical superiority of the Neuro 2 sound processor over Neuro One in terms of speech identification in quiet and in noise and reported patient benefit and satisfaction. Given the study design, sources of improvement may include factors unrelated to the sound processor itself.

    Patterns in the social representation of "hearing loss" across countries: how do demographic factors influence this representation?2018In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 57, no 12, p. 925-932Article in journal (Refereed)
    Abstract [en]

    This study aims to understand patterns in the social representation of hearing loss reported by adults across different countries and explore the impact of different demographic factors on response patterns. The study used a cross-sectional survey design. Data were collected using a free association task and analysed using qualitative content analysis, cluster analysis and chi-square analysis. The study sample included 404 adults (18 years and over) in the general population from four countries (India, Iran, Portugal and UK). The cluster analysis included 380 responses out of 404 (94.06%) and resulted in five clusters. The clusters were named: (1) individual aspects; (2) aetiology; (3) the surrounding society; (4) limitations and (5) exposed. Various demographic factors (age, occupation type, education and country) showed an association with different clusters, although country of origin seemed to be associated with most clusters. The study results suggest that how hearing loss is represented in adults in general population varies and is mainly related to country of origin. These findings strengthen the argument about cross-cultural differences in perception of hearing loss, which calls for a need to make necessary accommodations while developing public health strategies about hearing loss.

    The ICF Core Sets for hearing loss - researcher perspective. Part I: Systematic review of outcome measures identified in audiological research2014In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 53, no 2, p. 65-76Article, review/survey (Refereed)
    Abstract [en]

    Objective: To review the literature in order to identify outcome measures used in research on adults with hearing loss (HL) as part of the ICF Core Sets development project, and to describe study and population characteristics of the reviewed studies. Design: A systematic review methodology was applied using multiple databases. A comprehensive search was conducted and two search pools were created, pool I and pool II. Study sample: The study population included adults (greater than= 18 years of age) with HL and oral language as the primary mode of communication. Results: 122 studies were included. Outcome measures were distinguished by instrument type, and 10 types were identified. In total, 246 (pool I) and 122 (pool II) different measures were identified, and only approximately 20% were extracted twice or more. Most measures were related to speech recognition. Fifty-one different questionnaires were identified. Many studies used small sample sizes, and the sex of participants was not revealed in several studies. Conclusion: The low prevalence of identified measures reflects a lack of consensus regarding the optimal outcome measures to use in audiology. Reflections and discussions are made in relation to small sample sizes and the lack of sex differentiation/descriptions within the included articles.

    The ICF Core Sets for hearing loss - researcher perspective. Part I: Systematic review of outcome measures identified in audiological research2014In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 53, no 2, p. 65-76Article, review/survey (Refereed)
    Abstract [en]

    Objective: To review the literature in order to identify outcome measures used in research on adults with hearing loss (HL) as part of the ICF Core Sets development project, and to describe study and population characteristics of the reviewed studies.

    Design: A systematic review methodology was applied using multiple databases. A comprehensive search was conducted and two search pools were created, pool I and pool II.

    Study sample: The study population included adults (>= 18 years of age) with HL and oral language as the primary mode of communication.

    Results: 122 studies were included. Outcome measures were distinguished by 'instrument type', and 10 types were identified. In total, 246 (pool I) and 122 (pool II) different measures were identified, and only approximately 20% were extracted twice or more. Most measures were related to speech recognition. Fifty-one different questionnaires were identified. Many studies used small sample sizes, and the sex of participants was not revealed in several studies.

    Conclusion: The low prevalence of identified measures reflects a lack of consensus regarding the optimal outcome measures to use in audiology. Reflections and discussions are made in relation to small sample sizes and the lack of sex differentiation/descriptions within the included articles.

    The ICF Core Sets for hearing loss: researcher perspective, Part II: Linking outcome measures to the International Classification of Functioning, Disability and Health (ICF)2014In: International Journal of Audiology, ISSN 1499-2027, E-ISSN 1708-8186, Vol. 53, no 2, p. 77-87Article, review/survey (Refereed)
    Abstract [en]

    Objective: To link outcome measures used in audiological research to the ICF classification and thereby describe audiological research from the ICF perspective. Design: Through a peer-reviewed or a joint linking procedure, link outcome measures to the ICF classification system using standardized ICF linking rules. Additional linking rules were developed in combination with the established rules to overcome difficulties when connecting audiological data to ICF. Absolute and relative frequencies of ICF categories were reported. Study sample: The identified outcome measures from the previous study (Part I) constituted the empirical material. Results: In total, 285 ICF categories were identified. The most prevalent categories were related to listening, hearing functions, auditory perceptions, emotions and the physical environment, such as noise and hearing aids. Categories related to communication showed lower relative frequencies, as did categories related to the social and attitudinal environment. Conclusions: Based on the linked outcome measures, communication as a research topic is subordinated to other research topics. The same conclusion can be drawn for research targeting the social and attitudinal environment of adults with HL. Difficulties in the linking procedure were highlighted and discussed, and suggestions for future revisions of the ICF from the audiological perspective were described.
