説明
The availability of the BSR for assessing hearing thresholds at speech frequencies was studied by using a “selective masking”. Auditory stimuli consisted of 500Hz, 1kHz and 2kHz tone pips with 5msec rise and 5msec decay without a plateau. Several different maskings were applied using unfiltered weighted noise (B), 1800Hz highpass noise (C), 900Hz high-pass noise (D), 450Hz high-pass noise (E), 450-560Hz band-pass noise (F) and 900-1120Hz band-pass noise (G).<br>Thresholds of the BSR at 500Hz, 1kHz and 2kHz were measured without masking (A) and then with varied masking noises (B-G). At each masking condition, thresholds obtained from BSR tests corresponded well to those from pure tone audiometry.<br>The “BSR audiometry” appeared to be useful for the determination of hearing thresholds at frequencies of 500Hz, 1kHz and 2kHz.
