Although several studies have documented the existence of sex differences in spontaneous otoacoustic emissions (SOAEs) and transient-evoked OAEs (TEOAEs) in humans, less has been published about sex differences in distortion-product OAEs (DPOAEs). Estimates of sex and ear differences were extracted from a data set of OAE measurements previously collected for other purposes. In accord with past findings, the sex differences for TEOAEs were substantial for both narrowband and wideband measures. By contrast, the sex differences for DPOAEs were about half the size of those for TEOAEs. In this sample, the ear differences were small for TEOAEs in both sexes and absent for DPOAEs. One implication is that the cochlear mechanisms underlying DPOAEs appear to be less susceptible to whatever influences are responsible for producing sex differences in TEOAEs and SOAEs in humans. We discuss the possibility that differences in the effective level of the stimuli may contribute to these outcomes.
尽管多项研究已证实人类自发性耳声发射（SOAE）和瞬态诱发耳声发射（TEOAE）存在性别差异，但关于畸变产物耳声发射（DPOAE）性别差异的报道较少。性别和耳差异的估计值取自先前为其他目的收集的耳声发射测量数据集。与过去的研究结果一致，TEOAE的性别差异在窄带和宽带测量中都很显著。相比之下，DPOAE的性别差异约为TEOAE的一半。在这个样本中，两性的TEOAE耳差异都很小，而DPOAE则不存在耳差异。这意味着，DPOAE潜在的耳蜗机制似乎对导致人类TEOAE和SOAE出现性别差异的任何影响不太敏感。我们讨论了刺激有效水平的差异可能导致这些结果的可能性。
