Abstract

The relationship between hearing sensitivity in the extended high-frequency region (8-16 kHz) and (1) the presence of synchronized spontaneous otoacoustic emissions (SSOAEs) and (2) the strength of click-evoked and distortion product otoacoustic emissions (CEOAEs and DPOAEs) was investigated in 104 ears of 57 young adults. The age range was confined to 16 to 19 years. All subjects had normal hearing in the conventional audiometric frequency range (0.5-8 kHz). Ears with detected SSOAEs had better hearing sensitivity in the extended high-frequency region and also higher levels of CEOAEs and DPOAEs than ears with undetected SSOAEs. The results support the hypothesis that the presence of SSOAEs is indicative of an ear with highly normal cochlear function over a broad frequency range.

摘要

在57名年轻成年人的104只耳朵中，研究了扩展高频区域（8 - 16千赫）的听力敏感度与（1）同步自发性耳声发射（SSOAEs）的存在以及（2）短声诱发耳声发射和畸变产物耳声发射（CEOAEs和DPOAEs）强度之间的关系。年龄范围限定在16至19岁。所有受试者在传统听力测试频率范围（0.5 - 8千赫）内听力正常。检测到SSOAEs的耳朵在扩展高频区域具有更好的听力敏感度，并且与未检测到SSOAEs的耳朵相比，其CEOAEs和DPOAEs水平也更高。结果支持了这样的假设，即SSOAEs的存在表明耳朵在较宽频率范围内具有高度正常的耳蜗功能。
