The hearing handicap scale, a commonly used self-assessment measure, was administered to 50 subjects with normal hearing and hearing impairment. These subjects were then divided into three groups based on pure tone test results so that the range of hearing handicap scale scores could be determined for different hearing sensitivities. Subjects in one group of 20 exhibited hearing sensitivity of 10 dB hearing threshold level or better. A second group of 10 subjects had hearing sensitivity of 11--25 dB hearing threshold level. The third group of 20 subjects had sensitivity poorer than 25 dB hearing threshold level. Percentage scores for the subjects with the most sensitive hearing clustered from 0 to 20% with a mean score of 7.8%. The intermediate group had a mean score of 25.6%. Scores for the hearing-impaired group clustered between 40 and 70% with a mean score of 54%. Score variability was about twice as great in the two groups with poorer sensitivity. It is suggested that hearing handicap performance may be classified into one of four categories, ranging from no handicap to severe handicap.
听力障碍量表是一种常用的自我评估方法，对50名听力正常和听力受损的受试者进行了测试。然后根据纯音测试结果将这些受试者分为三组，以便确定不同听力敏感度下听力障碍量表分数的范围。20名受试者组成的一组听力敏感度达到10分贝听力阈值水平或更高。另一组10名受试者的听力敏感度为11 - 25分贝听力阈值水平。第三组20名受试者的敏感度低于25分贝听力阈值水平。听力最敏感的受试者的百分比分数集中在0至20%之间，平均分数为7.8%。中间组的平均分数为25.6%。听力受损组的分数集中在40%至70%之间，平均分数为54%。敏感度较差的两组分数变异性约为其两倍。建议听力障碍表现可分为四类之一，从无障碍到严重障碍。
