耳鸣频率与蜗性听力损失患者DPOAE的相关性研究

目的：分析蜗性听力损失伴耳鸣患者畸变产物耳声发射，耳鸣频率两者之间的关系。方法：DPOAE以系统自带的设置，其中f1：f2=1.22，f2频率范围0.553~8.837 kHz，L1=65 dBSPL，L2=55 dBSPL，测定常规频率（125 Hz~8 kHz）的纯音听阈，并进行耳鸣匹配测试。结果：耳鸣频率与DPOAE比较，耳鸣频率在3000 Hz，4000 Hz，6000 Hz，8000 Hz的有175耳（78.5%），DPOAE F2幅值下降频率在3125 Hz、4416 Hz、6250 Hz、8837 Hz的有194耳（86.7%），耳鸣频率与DPOAE F2幅值下降频率具有一一对应关系的为46耳（20.1%）。结论：耳鸣的频率范围与DPOAE下降频率范围在蜗性聋中有对应关系，

Study on Relationship between Tinnitus Frequency and DPOAE of Patinent with Hearing Loss

Objective：To discuss the relationship between the DPOAF of patient with cochlea hearing losing and tinnitus frequency. Method：DPOAE was induced by parading original sound. f1 and f2（f1：f2=1.22,f2 frequency range,0.553-8.837 kHz,L1=65 dBSPL,L2=55 dBSPL）,pure tone signals,were used to measure the routine frequency of pure tone audiometry and test tinnitus matching. Result：Comparing with the relationship between Pure Tone Audiometry and DPOAE,it had 175 ears（78.5%）. The tinnitus frequency were 3000 Hz,4000 Hz,6000 Hz, 8000 Hz. DPOAE F2 amplitude dropping frequency range was 3125 Hz,4416 Hz,6250 Hz,and 8837 Hz. There was 194 ears（86.7%）. DPOAE and tinnitus frequency F2 amplitude decrease frequency were one to one correspondence. It had 46 ears（20.1%）. Conclusion：The relationship between tinnitus frequency and DPOAE decrease frequency is corresponding. They are not one to one correspondence.
