정상인과 감각신경성 난청인에서 불쾌역치와 등골반사역치의 비교

Abstract

The purpose of this study was to investigate the relationship between the uncomfortable loudness level (ULL) and the acoustic reflex threshold (ART) for puretones in normal ears and ears with sensorineural hearing loss (SNHL). ULLs and ARTs were obtained from 73 normal ears and 50 ears with SNHLs at 0.5, 1, 2, 4 kHz. The results indicated that the significant differences between the ULL and the ART were shown in normal ears, but not in SNHL ears. According to the multiple regression analysis, the correlations between the ULL and the ART were significant in SNHL ears, but not in normal ears. (4(2):148-153, 2000)
