为探讨检测TEOAE的主频对诊断梅尼埃病的应用价值,本研究用ILO 88测试系统以click声为刺激信号,对正常耳和梅尼埃病耳作瞬态耳声发射(TEOAE)检测,观察其主频范围.发现正常耳的主频集中在1.2～l.6kHz之间,梅尼埃病主频集中在0.8～1.1kHz之间,正常耳的主频明显高于梅尼埃耳的主频.梅尼埃病人服用甘油后,TEOAE主频发生变化,由低频转为高频,未引出耳声发射耳,服用甘油后耳声反射引出.以上结果提示,检测TEOAE的主频对梅尼埃病的诊断有一定意义.
In order to explore the application value of detecting the main frequency of TEOAE in the diagnosis of Meniere’s disease, this study used the click sound as stimulus signal in the ILO 88 test system to detect transient otoacoustic emission (TEOAE) in normal and Meniere’s ear , Observed its frequency range found that the main frequency of normal ears concentrated in the 1.2 ~ l.6kHz, Meniere’s frequency was concentrated in the 0.8 ~ 1.1kHz between the normal ear frequency was significantly higher than the Meniere Of the frequency of Meniere patients after taking glycerol, TEOAE frequency change from low frequency to high frequency, did not lead to otoacoustic emission ear, after taking glycerin, otoacoustic reflection leads to the above results suggest that the detection of TEOAE frequency pairs Meniere’s diagnosis has some significance.
