Transient-evoked otoacoustic emissions (TEOEs) were measured in 1164 ears from 582 neonates without any risk of hearing impairment in order to define basic characteristics useful in deciding if TEOEs could be considered as "normal" in a screening test. Five neonates had no recordable TEOE and ABR thresholds greater than 30 dBnHL. Technical conditions have been analysed using the intensity of the click stimulation, the time necessary to record TEOEs, and the noise floor in the external ear canal (i.e. A-B magnitude). The TEOE magnitude varied between 6.6 dB SPL and 38 dB SPL (mean = 21.75 dB SPL). Only 5% of the tested neonates had a TEOE magnitude lower than 7.75 dB SPL. The TEOE magnitude for the right ear of a neonate was statistically different from those recorded in the left ear (22.4 dB SPL versus 21 dB SPL). The mean TEOE magnitude for male ears was statistically different from those recorded in female ears (21.4 dB SPL versus 22.1 dB SPL).
对582名无任何听力损害风险的新生儿的1164只耳朵进行了瞬态诱发耳声发射（TEOE）测量，以确定在筛查测试中可用于判断TEOE是否可被视为“正常”的基本特征。5名新生儿未记录到TEOE且听性脑干反应（ABR）阈值高于30 dBnHL。使用短声刺激强度、记录TEOE所需时间以及外耳道的本底噪声（即A - B幅度）对技术条件进行了分析。TEOE幅度在6.6 dB SPL至38 dB SPL之间变化（平均值 = 21.75 dB SPL）。仅5%的受试新生儿TEOE幅度低于7.75 dB SPL。新生儿右耳的TEOE幅度与左耳记录的幅度在统计学上存在差异（22.4 dB SPL对21 dB SPL）。男性耳朵的平均TEOE幅度与女性耳朵记录的幅度在统计学上存在差异（21.4 dB SPL对22.1 dB SPL）。
