Gap detection thresholds in young musicians with normal hearing and with very high frequency sloping hearing loss in 1/3-octave white noise centered at 4 kHz
Abstract
Gap detection thresholds in 1/3-octave white noise centred at 4 kHz were determined in young musicians with normal hearing preserved and with very high frequency sloping hearing loss. The thresholds were determined in the control group of 20 with normal hearing, i.e. flat audiogram up to 16 kHz, and in the experimental group of 15 with high frequency sloping hearing loss exceeding 30 dB at 12 kHz or at 16 kHz, the so called peculiar hearing loss. A group of 7 older subjects exhibiting also peculiar hearing loss was included for comparison. The results show gap detection thresholds in the normal hearing subjects ranging from 1 ms to 6 ms, which are in good agreement with the earlier data from the present authors. However, few examples of higher gap detection thresholds (11, 26 ms) in normal hearing were also observed. For the experimental group with high frequency sloping hearing loss at 12 kHz or at 16 kHz, the gap detection thresholds found were on the average significantly higher ranging from 6ms to 26 ms. In the group of older subjects gap detection thresholds were on the average still significantly higher.References
