SS07: PSYCHOACOUSTICS, SPEECH PERCEPTION AND AUDITORY SIGNAL PROCESSING

Wenesady 24th / 08:00 am / Room Islas Canarias

In order to develop audiology to a full interdisciplinary science with an interplay between experimental findings and theoretical concepts, the development and application of adequate models of hearing impairment is necessary.  Recent findings from auditory physiology and psychoacoustics are used to characterize the normal and pathological auditory signal processing that takes place during speech perception by normal and hearing-impaired listeners. By comparing the actual performance of subjects with model predictions, adequate processing models can be tested and improved. Hence our understanding of the impact of sensorineural hearing impairment on human sound perception can be enhanced.  The scientific basis of such an approach is reviewed in the structured session. Also, the consequences for auditory diagnostics and fitting of hearing aids are discussed.
