诱发耳声发射可以在瞬态刺激后测量，也可以作为两个纯音的失真产物。两种发射类型的测量正被更频繁地使用，因为技术变得更容易实施，并且实现了临床益处。此外，来自同一只耳朵的两种类型的发射之间的比较提供了关于耳蜗机制的信息。我们测量了瞬态诱发耳声发射（TEOAEs）刺激的点击和畸变产物耳声发射（DPOAEs）从166耳的个人和没有听力障碍。将TEOAE和DPOAE的振幅按频率相互比较，并与相应的听力阈值进行比较。结果显示，两种发射类型之间（r = 0.78）以及每种发射的能量分布与相应频率的听力阈值水平之间（DPOAE，斯皮尔曼p = -0.84; TEOAE，p = -0.77）具有高度对应性。当各频率的听力水平大于30 dB时，DPOAE比TEOAE更常见。结果表明，TEOAE和DPOAE在很大程度上来自类似的机制。通过听力阈值水平的两种发射的发生之间的差异表明，TEOAE可能是优选的筛选目的，而DPOAE可能是更有价值的监测耳蜗变化的临床。
Evoked otoacoustic emissions can be measured after a transient stimulus or as distortion products of two pure tones. Measurements of both emission types are being used more frequently as the techniques become easier to implement and the clinical benefits are realized. In addition, comparisons between the two types of emissions from the same ear provide information about cochlear mechanisms. We have measured transiently evoked otoacoustic emissions (TEOAEs) stimulated with clicks and distortion-product otoacoustic emissions (DPOAEs) from 166 ears of individuals with and without hearing impairment. The TEOAE and DPOAE amplitudes were compared with each other and with corresponding audiometric thresholds by frequency. Results revealed a high correspondence between the two emission types (r = .78) and between the distribution of the energy for each emission and audiometric threshold levels at corresponding frequencies (DPOAE, Spearman p = -.84; TEOAE, p = -.77). The DPOAEs were present more often than were TEOAEs when hearing levels across frequency were greater than 30-dB hearing level. The results suggest that both TEOAEs and DPOAEs are derived largely from similar mechanisms. The differences between the occurrence of the two emissions by audiometric threshold level would suggest that TEOAEs may be preferable for screening purposes, whereas DPOAEs may be more valuable for monitoring cochlear changes clinically.
