Two groups of subjects, 50 noise-exposed and 50 non-noise-exposed, both with unilateral conductive hearing loss, were studied in terms of the amount of conductive hearing loss and difference in the bone conduction thresholds at 4 kHz between the two ears. The results support the hypothesis that middle ear disorders provide the ear some protection from noise-induced hearing loss.
两组研究对象，每组各50人，一组为噪声暴露组，另一组为非噪声暴露组，两组均患有单侧传导性听力损失，研究人员对他们的传导性听力损失程度以及双耳之间4千赫兹骨导阈值的差异进行了研究。结果支持了以下假设：中耳疾病为耳朵提供了一定程度的保护，使其免受噪声性听力损失的影响。
