Clinical and audiological characteristics of 1000 Hz audiometric notch patients

Hidden hearing loss and tinnitus: Utility of the high‐definition audiograms in diagnosis

“…The hearing threshold at 1000 Hz exceeds 25 dB; this threshold is 15 dB larger than the lower half‐frequency (500 Hz) and is 10 dB larger than the higher frequency. The precision we obtained with our protocol was higher with a thinner bandwidth (1746 Hz) and smaller depth of intensity threshold (9 dB) compared with previously reported evaluation . For this reason we called it micro‐notch.…”

“…In 2017, Lee et al reported the audiological characteristics of 1000 Hz audiometric notch patients based on testing with a classical audiogram . The hearing threshold at 1000 Hz exceeds 25 dB; this threshold is 15 dB larger than the lower half‐frequency (500 Hz) and is 10 dB larger than the higher frequency.…”

“…The THI was 51 ± 17 [12-80] with 75.7% of the patients at grade 3 or above. The VAS score for the annoyance of the tinnitus was 6 ± 1.7 [2][3][4][5][6][7][8][9][10], and the VAS score for its loudness was 6 ± 1.6 [2][3][4][5][6][7][8][9][10].…”
