Gap detection thresholds in 1/3-octave white noise centred
at 4kHz 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 16kHz,
and in the experimental group of 15 with high frequency sloping hearing loss
exceeding 30dB at 12kHz or at 16kHz, 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 1ms to 6ms, which are in good agreement with the earlier
data from the present authors. However, few examples of higher gap detection
thresholds (11, 26ms) in normal hearing were also observed. For the experimental
group with high frequency sloping hearing loss at 12kHz or at 16kHz, the gap
detection thresholds found were on the average significantly higher ranging from
6ms to 26ms. In the group of older subjects gap detection thresholds were on the
average still significantly higher.
