耳声发射(Otoacoustic emissions,OAEs)是指源于耳蜗并能在外耳道记录到的声信号。早在1948年Gold即猜测内耳存在有正反馈作用特性的生物力学过程,以加强基底膜的运动,并认为可能在外耳道记录到这种活动的信号。Kemp首次在人外耳道记录到由短声刺激诱发的耳声发射信号,随后又记录到自发性耳声发射,证实了Gold的假设,并认为OAEs可作为一种客观听力检查法,有重要的临床应用价值。以后,许多研究者通过大量实验证
Otoacoustic emissions (OAEs) are acoustic signals originating in the cochlea and recorded in the external auditory meatus. As early as 1948, Gold speculated that there was a biomechanical process of positive feedback in the inner ear to reinforce the movement of the basement membrane and that it was possible to record signals of this activity in the external auditory meatus. Kemp first recorded the otoacoustic emissions induced by short-syllable stimulation in the human auditory canal and subsequently recorded spontaneous otoacoustic emissions, confirming the Gold hypothesis and arguing that OAEs can be used as an objective hearing test and has important clinical Value. Since then, many researchers through a large number of experimental evidence
