Audio Quality of Film Dialogue Across the Listening Space: Do Untrained Listeners Perceive a Difference in Audio Quality when Switching Between Ideal and Less Ideal Listening Positions?
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
The use of surround sound in cinema can be considered fairly ubiquitous today, and with that the practice of using the center channel for playback of dialogue content. The studies done for dialogue or speech content in the center channel have utilised Speech-in-Noise tests, without placing the test procedure in a realistic application. This study investigated how untrained listeners rated different excerpts of film with accompanying surround sound in three different playback options for dialogue content: center channel, phantom center and the dialogue positioned in the soundscape according to the actors' positions on screen. The purpose of these ratings was to examine whether one of these three playback options better preserved audio quality in a non-ideal listening position compared to an ideal one. The results show that none of the qualities changed significantly when comparing the two listening positions. The conclusion was made that either the tasks were too complex for untrained subjects or that untrained listeners do not perceive a detriment in audio quality of dialogue when sitting in a non-ideal listening position.
