Bekesy Audiometry in Simulated Hearing Loss Ten normal-hearing volunteers, all otolaryngologists and audiometric technicians, were asked to simulate a 50-dB hearing loss in one ear on a Grason-Stadler Bekesy audiometer, Model E 800, standardized to ISO (1964). The data were analyzed and compared with the available literature. The following conclusions were reached: (1) A test-retest discrepancy, ... Forum

Ten normal-hearing volunteers, all otolaryngologists and audiometric technicians, were asked to simulate a 50-dB hearing loss in one ear on a Grason-Stadler Bekesy audiometer, Model E 800, standardized to ISO (1964). The data were analyzed and compared with the available literature. The following conclusions were reached: (1) A test-retest discrepancy, consistently present in all the subjects with simulated hearing loss, was the most reliable criterion for detecting such loss. (2) Type-V Bekesy tracings indicated simulated hearing loss and were found in 70% of the subjects. (3) Saucer-shaped curves and increased Bekesy excursions are not reliable indicators of simulated hearing loss. (4) The Bekesy audiometer is a reliable tool in detecting simulated hearing loss.
