失真产物耳声发射(DPOE)是由两个纯音诱发的耳声发射，用于提供耳蜗力学特性的特定频率评估。本文首次报道了正常新生儿群体中867赫兹至8千赫听力测试频率的完整输入输出DPoE函数(标准数据)。分析DPoE结果作为诱发耳声发射(EOE)特性的函数。EOEs正常的新生儿有较大的DPOE。新生儿的DPoE波幅大于成人。没有低频成分的非典型EOE频谱的新生儿仅在高频(>2 kHz)时具有正常的DPoE输入输出功能。DPOEs与EOES联合应用可用于准确评估新生儿的听觉外周功能。
Distortion-product otoacoustic emissions (DPOEs) are otoacoustic emissions evoked by two pure tones and used in order to provide a frequency specific assessment of the mechanical properties of the cochlea. This paper first reports complete input-output DPOE functions for audiometric frequencies between 867 Hertz and 8 kHz in a normal neonate population (normative data). DPOE results were analyzed as a function of evoked otoacoustic emission (EOE) properties. Neonates having normal EOEs have large DPOEs. DPOE amplitudes in neonates are larger than in adults. Neonates with atypical EOE frequency spectrum without low frequency components had normal DPOE input-output functions only for high frequencies (above 2 kHz). DPOEs could be useful, in association with EOEs, to precisely evaluate the auditory peripheral function in neonates.
