| 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 ,但不是判断耳蜗功能正常的惟一指标

| Abstract: | 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: (1) SOAE frequencies ranged from about 0.5 kHz to 6 kHz, it's amplitudes distributed between -28 and 6 dB SPL; (2) 49% had SOAE and there were no significant difference in sexuality in normal hearing subjects. During long duration observation, frequency of SOAE was no change; (3) Amplitude of SOAE could be suppressed by contralateral white noise; (4) There 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. |
