Spectral Dynamics and Speech Understanding by Hearing Impaired People
In Brief
A clinical study evaluating Acoustic distortion of speech for Hearing Loss, Sensorineural. Completed, enrolled 50 participants across 1 site.
Detailed 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.
