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.
在180名受试者中评估了瞬态诱发耳声发射（TEOAEs）和畸变产物耳声发射（DPOAEs）区分正常听力与听力损伤的能力。TEOAEs被分析为频率范围从500至4000Hz的倍频程或1/3倍频程频段。决策理论用于为每个耳声发射测量（倍频程TEOAEs、1/3倍频程TEOAEs、DPOAEs）的三种测量值（耳声发射幅度、耳声发射/噪声、可重复性）、500至4000Hz的倍频程频率以及10至40dB HL的七个听力测定标准生成受试者操作特征（ROC）曲线。在500Hz时，TEOAEs和DPOAEs无法区分正常耳和受损耳。在1000Hz时，两种TEOAEs测量在识别听力状态方面比DPOAEs更准确。在2000Hz时，所有耳声发射测量表现同样良好。在4000Hz时，DPOAEs更能区分正常耳和受损耳。几乎无一例外，耳声发射/噪声和可重复性测量表现相当，且优于耳声发射幅度测量，尽管差异很小。分析为倍频程频段的TEOAEs比分析为1/3倍频程的TEOAEs表现更好。在标准测试条件下，耳声发射测试性能似乎受背景噪声限制，尤其是对于低频。
