Clinical Trial Summary

The purpose of this program of research is to understand the perception of the dynamic spectral properties of speech by hearing-impaired listeners, with the long-term goal of improving speech understanding by these individuals in adverse listening conditions. The proposed research compares the performance of normally-hearing and hearing-impaired listeners on measures of speech understanding in the presence of different types of signal distortion and speech understanding of signals with enhanced spectral dynamics. A computational model based on the amount of potential information available in speech will be used to quantify differences in speech intelligibility due to hearing status and stimulus characteristics.


Clinical Trial Description

This is a behavioral study of human auditory perception. Each experiment in this study involves prospective data collection from three types of listeners. The experimental listeners will be people with sensorineural hearing loss and the control listeners will either be subjects with normal hearing or normal-hearing listeners for whom hearing loss will be simulated through the use of a spectrally-shaped broadband noise. The tasks of the subjects in this study involve either listening to synthesized sounds over earphones while seated comfortably in a sound-treated booth, and making responses indicating the subject's auditory perception of these sounds by touching specific areas on a touch-screen terminal; or, listening to recorded, acoustically modified syllables, words, or sentences over earphones and making responses indicating the subject's identification. ;
