BACKGROUND
The aim of this study was to assess the ability of hearing aids to reduce the handicap associated with hearing impairment in adults.
METHODS
Fifty adults aged over 60 who were supplied with an NHS hearing aid had their hearing handicap and communication function recorded at initial hearing aid assessment, and after three months of aid use. Hearing communication function was assessed by a key informant.
RESULTS
Hearing aid use was associated with considerable score improvements for social and emotional function [20.5, 95 per cent confidence interval (Cl) 15.4-25.6] and communication function (22.9, 95 percent Cl 14.6-31.2). Younger people recorded the greatest reduction in handicap. Overall satisfaction with hearing aid performance was high.
CONCLUSIONS
Hearing aids are effective in reducing hearing handicap in adults. They represent a good buy for purchasers seeking to achieve health gain for adults with hearing impairment.
背景
本研究旨在评估助听器减轻成人听力障碍相关残疾的能力。
方法
50名60岁以上配备英国国家医疗服务体系（NHS）助听器的成年人，在初次助听器评估时以及使用助听器三个月后，记录他们的听力残疾和沟通功能。听力沟通功能由关键信息提供者进行评估。
结果
使用助听器与社交和情感功能[20.5，95%置信区间（Cl）15.4 - 25.6]以及沟通功能（22.9，95% Cl 14.6 - 31.2）的得分显著提高相关。年轻人的残疾减少幅度最大。对助听器性能的总体满意度较高。
结论
助听器在减轻成人听力残疾方面有效。对于寻求为有听力障碍的成年人实现健康改善的购买者来说，它们物有所值。
