BSR audiometry was applied to 63 ears with hearing losses and 28 normal ears. The auditory stimulus to elicit the BSR was one cycle of a 3kHz sinusoidal wave. Click intensities were calibrated relatedly to the subjective click threshold of normal adults listeners (0dBHL).
(1) The averaged BSR-threshold of the normal hearing group was 13.7dBHL.
(2) BSR-thresholds in cases with flat hearing losses were close to the averaged pure tone thresholds (averaged from 250Hz to 8kHz).
(3) BSR-thresholds in cases of high tone losses had a close correlation with pure tone thresholds at 2kHz.
(4) BSR-threshold could predict the pure tone threshold at 2kHz (with the exception of abrupt high tone losses above 2kHz).
(5) In cases of abrupt high tone losses BSR-thresholds were considerably higher than the subjective sound thresholds to the clicks.
