Design of product sound by blending of sound sources

Product sound usually consists of a mix of several sources. Models for prediction of sound quality based on combinations of psychoacoustic metrics like loudness, sharpness and roughness have limitations when compound sounds are analysed. When a compound sound is divided into separable sources through auditory streaming such models fail. The character of each source is given by physical properties. The character is usually hard to change without complete redesign of the product. The quality of the final product sound is determined by the mix of sound sources. Efficient product sound design requires tools for recording or simulation of sources, realistic modelling of transfer functions from source to listener and tools for mixing the sources. With such tools a sound source can be auralised as part of sound environments. Recordings of sound sources in a car were used to get source information. The sound from each source was filtered through idealised transfer functions, mixed and reproduced in a 5.1 surround sound studio. The resulting sound was evaluated through listening tests. This approach was shown to be a powerful tool for evaluation of the effect of auditory streaming on subjective judgments of compound product sound.
