Between 1980 and 1986, the Department of Otolaryngology at Mount Sinai Hospital, Toronto, evaluated 3,509 occupational hearing loss claimants for the Workers' Compensation Board of Ontario. Detailed information about work, medical and audiologic findings for each claimant was entered into the departmental database system. The goals of this retrospective analysis were to examine some demographic characteristics and to describe the aural rehabilitation status of this population. Most claimants had bilateral mild or moderate hearing loss but all degrees and patterns of loss occurred. Of 2,657 first-time, reliable claimants, 881 (33.2%) arrived with a hearing aid, typically a monaural, behind-the-ear fitting. Twenty percent with bilateral mild loss owned an aid whereas 38% of claimants with bilateral severe loss did not have one. Ninety percent of aid owners reported that their device was of some help. This level of satisfaction was not affected by age, degree of loss, or speech discrimination ability. Substantial usage was reported for non-work situations. Hearing aids were especially helpful for TV and in small group situations. Ultimately, 81% of all claimants were determined to be hearing aid candidates.
1980年至1986年间，多伦多西奈山医院耳鼻喉科为安大略省工人赔偿委员会评估了3509名职业性听力损失索赔者。有关每位索赔者工作、医学和听力检查结果的详细信息被录入部门数据库系统。这项回顾性分析的目的是研究一些人口统计学特征，并描述该人群的听力康复状况。大多数索赔者患有双侧轻度或中度听力损失，但各种程度和类型的听力损失均有发生。在2657名首次提出可靠索赔的人中，881人（33.2%）前来时佩戴了助听器，通常是单耳耳背式助听器。双侧轻度听力损失的人中20%拥有助听器，而双侧重度听力损失的索赔者中有38%没有助听器。90%的助听器使用者表示他们的设备有一定帮助。这种满意度不受年龄、听力损失程度或言语辨别能力的影响。据报告，助听器在非工作场合的使用频率很高。助听器对看电视和在小群体环境中特别有帮助。最终，所有索赔者中有81%被确定为适合佩戴助听器。
