A study of two samples (one in London, the other in Cairo) of patients who were suffering from an impairment of hearing showed that the subjective magnitude of auditory handicap was significantly correlated to the average hearing level at 2 000 Hz for the two ears. For both samples, the subjective magnitude of the auditory handicap was shown to be a power function of the hearing loss expressed in terms of the sound pressure corresponding to the threshold of hearing. The exponents in the power function applying to the two samples were similar. Age, sex and pain threshold did not influence the estimation of the subjective magnitude of auditory handicap in this study.
一项针对两组听力受损患者样本（一组在伦敦，另一组在开罗）的研究表明，听觉障碍的主观程度与双耳在2000赫兹时的平均听力水平显著相关。对于两组样本，听觉障碍的主观程度均表现为以听阈对应的声压表示的听力损失的幂函数。适用于两组样本的幂函数中的指数相似。在本研究中，年龄、性别和疼痛阈值均未影响听觉障碍主观程度的评估。
