Otoacoustic emissions are acoustic signals detectable in the external auditory canal that reflect the state of health of the cochlea. Transiently-evoked otoacoustic emissions and distortion-project otoacoustic emissions are two types of otoacoustic emissions currently under investigation as well as in limited clinical use. These objective tests of cochlear function add significantly to the armamentarium currently in place for the evaluation of hearing. The clinical use of these diagnostic tools will likely increase dramatically in the coming years. The following review provides a basis for understanding the nature and clinical utility of otoacoustic emissions.
耳声发射是在外耳道中可检测到的声学信号，反映了耳蜗的健康状况。瞬态诱发耳声发射和畸变产物耳声发射是目前正在研究且在有限临床应用中的两种耳声发射类型。这些耳蜗功能的客观测试显著增加了目前用于听力评估的手段。在未来几年，这些诊断工具的临床应用可能会大幅增加。以下综述为理解耳声发射的性质和临床应用提供了基础。
