HearingImpaired Elderly Listeners
The Modified Rhyme Test (MRT), recorded using natural speech and two forms of synthetic speech, DECtalk and Votrax, was used to measure both open-set and closed-set speechrecognition performance. Performance of hearing-impaired elderly listeners was compared to two groups of young normal-hearing adults, one listening in quiet, and the other listening in a background of spectrally shaped noise d...
متن کاملTemporal resolution in normal-hearing and hearing-impaired listeners using frequency-modulated stimuli.
This study compares the temporal resolution of frequency-modulated sinusoids by normal-hearing and hearing-impaired subjects in a discrimination task. One signal increased linearly by 200 Hz in 50 msec. The other was identical except that its trajectory followed a series of discrete steps. Center frequencies were 500, 1000, 2000, and 4000 Hz. As the number of steps was increased, the duration o...
متن کاملModeling spectro-temporal modulation perception in normal-hearing listeners
The ability of human listeners to detect and discriminate spectro-temporal ripples in sound has been shown to be correlated with speech intelligibility performance in several conditions. Thus, if a model would be able to account for the spectro-temporal processing limits in the auditory system, such a framework could be used to analyze the auditory processes contributing to and limiting speech ...
متن کاملAuditory temporal and spectral resolution in normal and impaired hearing.
Temporal, spectral, and combined temporal-spectral resolution of hearing was assessed by recording masked hearing thresholds. The masker was an octave band noise. Spectral resolution was assessed by introducing a spectral gap of half an octave bandwidth in the masker. A 50-msec gap assessed temporal resolution. The spectral and temporal gaps were used separately or simultaneously. Normal-hearin...
متن کاملFrequency and temporal resolution in elderly listeners with good and poor word recognition.
There is a subgroup of elderly listeners with hearing loss who can be characterized by exceptionally poor speech understanding. This study examined the hypothesis that the poor speech-understanding performance of some elderly listeners is associated with disproportionate deficits in temporal resolution and frequency resolution, especially for complex signals. Temporal resolution, as measured by...
