The present investigation further analysed results of a previously reported survey with a large sample of hearing aid owners (Bertoli et al, 2009) to determine the individual and technological factors related to hearing aid outcome. In particular the associations of hearing loss, level of signal processing, and fitting type (bilateral versus unilateral fitting) with hearing aid use, satisfaction with and management of the aid were evaluated. A sub-group with symmetrical hearing loss was analysed (n = 6027). Regular use was more frequent in bilateral users and in owners of devices with more complex signal processing, but the strongest determinant of regular use was severity of hearing loss. Satisfaction was higher in the group wearing simple devices, while fitting type and degree of hearing loss had no influence on satisfaction rates. Moderate and severe hearing loss was associated more frequently with poor management of the aid than mild hearing loss. It was concluded that bilateral amplification and advanced signal processing features may contribute to successful hearing aid fitting, but the resulting differences must be considered to be relatively small.
本研究进一步分析了先前一项大型助听器使用者调查结果（Bertoli 等人，2009 年），以确定与助听器效果相关的个体和技术因素。特别是，研究评估了听力损失、信号处理水平和适配类型（双侧与单侧适配）与助听器使用、对助听器的满意度和管理之间的关联。对听力损失对称的亚组（n = 6027）进行了分析。双侧使用者和使用信号处理更复杂设备的使用者更频繁地进行常规使用，但常规使用的最强决定因素是听力损失的严重程度。对简单设备的满意度更高，而适配类型和听力损失程度对满意度没有影响。中度和重度听力损失比轻度听力损失更常与助听器管理不善有关。研究结论认为，双侧放大和先进的信号处理功能可能有助于成功的助听器适配，但必须考虑到由此产生的差异相对较小。
