本研究探讨了耳朵不对称，利手，性别对畸变产物耳声发射（DPOAEs）从学龄儿童获得的影响。共有1003名儿童（528名男孩和475名女孩），平均年龄为6.2岁（SD = 0.4，范围= 5.2-7.9岁），在一个安静的房间里，在他们的学校使用GSI-60 DPOAE系统进行了测试。获得每只耳朵的失真乘积（DP）图，f2在1.1至6.0 kHz之间变化，f2/f1的比值为1.21。在测试频率1.1、1.5、1.9、2.4、3.0、3.8、4.8和6.0 kHz下测量信噪比（SNR）（DPOAE振幅减去平均本底噪声）。结果显示，两耳之间的SNR存在微小但显著的差异，在1.9、3.0、3.8和6.0 kHz时，右耳的平均SNR高于左耳。在这些频率下，耳朵之间的平均SNR差异小于1 dB。在3.8、4.8和6.0 kHz时，女孩的信噪比高于男孩。在这些频率下，由于性别效应，平均SNR的差异约为1至2 dB。对于所有测试频率，左利手和右利手儿童的平均SNR没有显著差异。
The present study examined effects of ear asymmetry, handedness, and gender on distortion-product otoacoustic emissions (DPOAEs) obtained from schoolchildren. A total of 1003 children (528 boys and 475 girls), with a mean age of 6.2 years (SD = 0.4, range = 5.2-7.9 years), were tested in a quiet room at their schools using the GSI-60 DPOAE system. A distortion-product (DP)-gram was obtained for each ear, with f2 varying from 1.1 to 6.0 kHz and the ratio of f2/f1 at 1.21. The signal-to-noise ratios (SNRs) (DPOAE amplitude minus the mean noise floor) at the tested frequencies 1.1, 1.5, 1.9, 2.4, 3.0, 3.8, 4.8, and 6.0 kHz were measured. The results revealed a small but significant difference in SNR between ears, with right ears showing a higher mean SNR than left ears at 1.9, 3.0, 3.8, and 6.0 kHz. At these frequencies, the difference in mean SNR between ears was less than 1 dB. A significant gender effect was also found. Girls exhibited a higher SNR than boys at 3.8, 4.8, and 6.0 kHz. The difference in mean SNR, as a result of the gender effect, was about 1 to 2 dB at these frequencies. There was no significant difference in mean SNR between left-handed and right-handed children for all tested frequencies.
