The auditory literature suggests that ears having spontaneous otoacoustic emissions (SOAEs) should also evidence overall better hearing in the quiet than ears with no SOAEs, but no direct tests of this presumed relationship have been made. Accordingly, hearing sensitivity was measured in both males and females having either no SOAEs or at least four SOAEs in the right ear. Averaged across frequencies, the hearing of the subjects with SOAEs was about 3 dB better, in both ears, than the hearing of the subjects with no SOAEs. In accord with past findings, sensitivity was also significantly better in right ears than left. However, the common finding of better hearing in females than males did not emerge, suggesting that this difference may exist only when the sex difference in SOAE prevalence is not taken into account. The existence of a direct relationship between hearing sensitivity in the quiet and the presence of SOAEs suggests that a common mechanism may be responsible for both.
听觉文献表明，具有自发性耳声发射（SOAE）的耳朵在安静环境中的整体听力应该比没有SOAE的耳朵更好，但尚未对这种假定的关系进行直接测试。因此，对右耳没有SOAE或至少有四个SOAE的男性和女性进行了听力敏感度测量。在所有频率上平均，有SOAE的受试者双耳听力比没有SOAE的受试者约好3dB。与过去的研究结果一致，右耳的敏感度也明显高于左耳。然而，并未出现女性听力优于男性的常见发现，这表明只有在不考虑SOAE患病率的性别差异时，这种差异才可能存在。安静环境中的听力敏感度与SOAE的存在之间存在直接关系，这表明可能存在一种共同机制导致这两者。
