We performed a prospective interventional study to evaluate correlations between hearing thresholds determined by pure-tone audiometry (PTA) and auditory steady-state response (ASSR) testing in two types of patients with hearing loss and a control group of persons with normal hearing. The study was conducted on 240 ears-80 ears with conductive hearing loss, 80 ears with sensorineural hearing loss, and 80 normal-hearing ears. We found that mean threshold differences between PTA results and ASSR testing at different frequencies did not exceed 15 dB in any group. Using Pearson correlation coefficient calculations, we determined that the two responses correlated better in patients with sensorineural hearing loss than in those with conductive hearing loss. We conclude that measuring ASSRs can be an excellent complement to other diagnostic methods in determining hearing thresholds.
我们进行了一项前瞻性干预研究，以评估在两类听力损失患者及一组听力正常的对照组中，通过纯音听力测定（PTA）确定的听力阈值与听觉稳态反应（ASSR）测试之间的相关性。该研究共涉及240只耳朵——80只患有传导性听力损失的耳朵、80只患有感音神经性听力损失的耳朵以及80只听力正常的耳朵。我们发现，在任何一组中，不同频率下PTA结果与ASSR测试之间的平均阈值差异均未超过15分贝。通过计算Pearson相关系数，我们确定感音神经性听力损失患者的两种反应之间的相关性优于传导性听力损失患者。我们得出结论，在确定听力阈值方面，测量ASSR可以作为其他诊断方法的极佳补充。
