ABSTRACT

OBJECTIVE: The aim of this study was to predetermine the discrimination standard point of distortion product otoacoustic emission(DPOAE) amplitudes, which discriminates the degree of the mild noise-induced hearing loss, and to estimate the accuracy and predictability of the discrimination standard point of DPOAE amplitudes. Therefore we were able to determine the usability of the DPOAE test in screening exam for mild noise-induced hearing loss. METHODS: This study was analyzed 50 high frequency-impaired ears(from 25dB HL to 40dB HL at 4000Hz for which the response of DPOAE was not disappeared) and 81 normal ears through the correlation test between the amplitudes of DPOAE test and the threshold of the pure-tone audiometry test. RESULT: The discrimination between >or=25dB and
