对180名受试者进行了瞬变诱发耳声发射(TEOAEs)和失真产物耳声发射(DPOAEs)对听力正常和听力损害的鉴别能力评估。在500至4000赫兹的频率范围内，TEOAEs被分析成倍频程或三分之一倍频程。使用决策理论为每个耳声发射测量(倍频程TEOAES、1/3倍频程TEOAES、DPOAEs)的三个测量(OAE幅度、OAE/噪声、重复性)中的每一个生成接收器操作特征(ROC)曲线，针对500~4000 Hz的八度频率，以及从10到40dBHL的7个听力学标准。在500 Hz时，TEOAEs和DPOAEs不能区分正常和受损的耳朵。在1000赫兹时，两种TEOAE测量在识别听力状态方面都比DPOAEs更准确。在2000赫兹时，所有的耳声发射测量都表现得同样好。在4000 Hz时，DPOAEs能更好地区分正常和受损的耳朵。几乎无一例外，耳声发射/噪声和重复性的测量表现相似，优于耳声发射幅度的测量，尽管差异很小。分析为倍频程的TEOAEs比分析为1/3倍频程的TEOAEs具有更好的性能。在标准测试条件下，OAE测试性能似乎受到背景噪声的限制，特别是对于低频。
The ability of transient-evoked otoacoustic emissions (TEOAEs) and distortion product otoacoustic emissions (DPOAEs) to distinguish normal hearing from hearing impairment was evaluated in 180 subjects. TEOAEs were analyzed into octave or one-third octave bands for frequencies ranging from 500 to 4000 Hz. Decision theory was used to generate receiver operating characteristic (ROC) curves for each of three measurements (OAE amplitude, OAE/noise, reproducibility) for each OAE measure (octave TEOAEs, 1/3 octave TEOAEs, DPOAEs), for octave frequencies from 500 to 4000 Hz, and for seven audiometric criteria ranging from 10 to 40 dB HL. At 500 Hz, TEOAEs and DPOAEs were unable to separate normal from impaired ears. At 1000 Hz, both TEOAE measures were more accurate in identifying hearing status than DPOAEs. At 2000 Hz, all OAE measures performed equally well. At 4000 Hz, DPOAEs were better able to distinguish normal from impaired ears. Almost without exception, measurements of OAE/noise and reproducibility performed comparably and were superior to measurements of OAE amplitude, although the differences were small. TEOAEs analyzed into octave bands showed better performance than TEOAEs analyzed into 1/3 octaves. Under standard test conditions, OAE test performance appears to be limited by background noise, especially for the low frequencies.
