耳声发射（ＯＡＥ）是一种产生于耳蜗经听骨链及鼓膜传导释放入外耳道的音频能量。它快速、无损、客观地反映了耳蜗外毛细胞的功能状态，在临床诊断和听力筛查方面具有广阔的前景。可靠地提取、识别、分析ＯＡＥ信号是其应用于临床的前提。本文将对目前的ＯＡＥ检测系统作一概述。 Otoacoustic Emissions (OAE) is a type of audio energy that is generated when the cochlea is transmitted through the ossicular chain and tympanic membrane into the external auditory meatus. It is rapid, non-destructive, objectively reflects the functional status of the outer hair cells of the cochlea, and has broad prospects in clinical diagnosis and hearing screening. The reliable extraction, identification and analysis of OAE signals are the prerequisites for its clinical application. This article will outline the current OAE detection system.
