ABSTRACT |
To determine any age-related declines in auditory temporal processing, this study examined the ability to process
temporal information using measure of gaps-in-noise (GIN) and of 40% time-compressed sentence recognition.
Participants were fifteen young listeners, eleven middle-aged listeners, and twelve elderly listeners, and all had
normal hearing. For the GIN test, both approximate gap detection threshold (msec) and detection performance in
percent correct (%) were measured. For the test of sentence recognition, all the listeners were needed to repeat
target sentences when the time-compressed sentences were presented without or with competing speech (0 dB SNR).
Our results showed that GIN performance of young group was greater than that of middle-aged group, and the
middle-aged group outperformed the elderly group. When the time-compressed sentences were presented with
competing speech, young group exhibited superior performance relative to middle-aged group, and also the
middle-aged group scored better than the elderly group. Overall, the GIN performance was related to the recognition
ability of time-compressed sentences. This supports the previous findings that the ability of auditory temporal
processing begins to decline at middle age. |
