機能性難聴における持続音と断続音の域値差
A simple yet reliable easy screening method for functional hearing loss was developed using an air conduction pure-tone audiometer. We performed pure-tone audiometry in 440 ears from 220 patients (101 males, 119 females) using 7 continuous and 7 pulse pure tones at 125Hz, 250Hz, 500Hz, 1000Hz, 2000Hz, 4000Hz and 8000 Hz. The hearing thresholds measured by continuous tones were compared with those measured by pulse tones at each frequency, and the number of frequencies which showed a 10 dB or
