The purpose of this study is to discuss the characteristics of the audiograms obtained in cases with simulated hearing loss. Twelve subjects with normal hearing were asked to simulate a moderate hearing loss on pure tone audiome try and Békésy audiometry. They were examined twice at one week interval.
The following results were obtained:
(1) The saucer type audiogram was found in 75 per cent.
(2) Type V Békésy audiogram was present in 89.6 per cent of 48 Békésy audiograms.
(3) TTD was positive in most of cases on Békésy audiograms. Furthermore TTD was also positive on interrupted tone tracing.
(4) Significant test-retest variation was not found in most subjects.
Analyzing the date mentioned above, the causes for this phenomenon were discussed.
