Abstract
The purpose of this experiment was to determine whether temporal effects on frequency discrimination were the same for persons with sensorineural loss and for persons with normal sensitivity. Estimates of the difference limen for frequency (DLF) were obtained for signals of 50- and 500-msec durations, for standard frequencies of 0.5, 1.5, and 3.0 kHz. In most of the conditions, the temporal effects on frequency discrimination were similar for hearing-impaired and normal-hearing subjects. Speech discrimination of the five hearing-impaired subjects also was measured. The highest rank-order correlation (rs = 1.0) was found between DLF at 3.0 kHz and vowel- and consonant-discrimination scores.
