Abstract

Transitory otoacoustic emissions (TOAE) were analyzed in 48 ears of male hunters (age range: 30-45 years: mean age: 37 years) and in a population with normal hearing. All the ears had TOAE. The incidence of TOAE for the 1, 2, 3, 4, 5 and 6 KHz frequential bands was significantly lower in hunters than in the normal subjects (p < 0.001). The mean amplitude of TOAE was significantly lower in hunters (9.2 dB SPL) than in the control group (16 dB SPL; p < 0.001). The amplitude of the TOAE for the frequencies 1, 2, 3, 4, 5 and 6 KHz was significantly lower in hunters than in controls (p < 0.001).

摘要

对48名男性猎人（年龄范围：30 - 45岁；平均年龄：37岁）的耳朵以及听力正常人群的耳朵进行了瞬态耳声发射（TOAE）分析。所有耳朵均有TOAE。猎人组1、2、3、4、5和6千赫兹频段的TOAE发生率显著低于正常受试者（p < 0.001）。猎人组TOAE的平均幅度（9.2分贝声压级）显著低于对照组（16分贝声压级；p < 0.001）。猎人组1、2、3、4、5和6千赫兹频率的TOAE幅度显著低于对照组（p < 0.001）。
