Study 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.
Primary Outcome
The experimental approach compares speech identification performance among younger, normally-hearing listeners, older normally-hearing listeners and hearing-impaired listeners. Tasks will be carried out in quiet and in the presence of continuous, speech-shaped background noise. The investigators compared the understanding of unprocessed stimuli with 1) time-compressed stimuli, 2) time-compressed stimuli expanded in time via gaps and 3) uncompressed stimuli where portions of the signal were repla
