Abstract

A prevailing complaint among individuals with sensorineural hearing loss (SNHL) is difficulty understanding speech, particularly under adverse listening conditions. The present investigation compared the speech-recognition abilities of listeners with mild to moderate degrees of SNHL to normal-hearing individuals with simulated hearing impairments, accomplished using spectrally shaped masking noise. Speech-perception ability was assessed using the predictability-high sentences from the Speech Perception in Noise test. Results revealed significant differences between groups in sentential-recognition ability, with the hearing-impaired subjects performing poorer than the masked-normal listeners. These findings suggest the presence of a secondary distortion degrading sentential-recognition ability in the hearing impaired, implications of these data will be discussed concerning the mechanism(s) responsible for speech perception in the hearing impaired.
