摘　　要：目的 :探讨国人自发性耳声发射 (SOAE)的特性。方法 :对 4 0例听力正常人和 96例听力下降者进行SOAE测试。结果 :①检出率依听力和病变部位不同有所差异 ,听力正常组约 4 9%可记录到SOAE ,性别间差异无统计学意义 (P >0 .0 5 ) ;②SOAE反应频率范围主要在 0 .5～ 6 .0kHz,发射频率稳定 ,强度分布范围 - 2 8～6dBSPL ;③SOAE反应形式有个体差异 ;④反应幅度可被对侧声抑制。结论 :SOAE的出现提示相应频率部位耳蜗外毛细胞功能良好 。Objective:To record and analyze the basic properties of spontaneous otoacoustic emission (SOAE) and to study the application of SOAE.Method:Forty cases (80 ears) with normally hearing subjects and 96 cases with abnormal hearing subjects were tested by ILO92 Otodynamics Analyzer.Result:①SOAE frequencies ranged from about 0.5 kHz to 6 kHz,it′s amplitudes distributed between -28 and 6 dB SPL;②49% had SOAE and there were no significant difference in sexuality in normal hearing subjects.During long duration observation,frequency of SOAE was no change;③Amplitude of SOAE could be suppressed by contralateral white noise;④There were some difference in different hearing loss group for SOAE.Conclusion:The presence of SOAE indicated that there is a better function for out hair cells of cochlear.
