目前,自发性耳声发射(SOAEs)的耳蜗发生机制尚未得到公认。由于SOAEs振幅常低于0 dB SPL,对检测要求较高;而且即使在听力正常的受试者中其检出率也很低(25～50%),其临床应用受到一定的限制。作者们为了解SOAEs是否可用于听力筛选或常规临床听力学检查,并研究受试者在有或无SOAEs时的耳聋特点,对63名受试者(126耳,年龄
At present, the mechanism of spontaneous otoacoustic emissions (SOAEs) has not been recognized. Because the amplitude of SOAEs is often lower than 0 dB SPL, the detection requirements are high; and the detection rate of SOAEs is very low (25-50%) in subjects with normal hearing, so its clinical application is limited. To understand whether SOAEs can be used for hearing screening or routine clinical audiology and to study the deafness characteristics of subjects with or without SOAEs, 63 subjects (126 ears, age
