In the face of the rapid development of hearing aid system technology it is helpful to regularly study the user benefit of the current generation.
To contribute to the question on how the user benefit of current hearing aids compares with the benefit of the previous generation of hearing aids, a multicentre study was carried out in cooperation with 79 hearing aid acoustics companies in Germany. The user benefit of modern hearing aids in everyday life was assessed by asking end users to participate in a survey by completing a questionnaire. The questionnaire consisted of 20 items, 10 of which were taken from validated international inventories (SSQ: Speech, Spatial and Qualities of Hearing scale, IOI-HA: International Outcome Inventory for Hearing Aids) and the other 10 were formulated particularly for this purpose.
A total of 664 usable questionnaires were returned whereby 421 responders were first time users and 243 responders were previous hearing aid users. The results of the present study showed that modern hearing aid system technology provides significant extra benefits at the 5 % level relative to the previous generation of hearing aids for all variables tested in this study.
Even though the amount of gain in terms of user benefit may be overestimated due to well-known placebo effects, an obvious net effect was evident. Correlations between the level of hearing aid benefit and possible influencing factors, such as age, gender, subjects own hearing aid, duration of use or hearing loss, could not be identified.
面对助听器系统技术的快速发展，定期研究当代产品对用户的益处是很有帮助的。
为了探讨当代助听器对用户的益处与上一代助听器相比情况如何，与德国79家助听器声学公司合作开展了一项多中心研究。通过让终端用户填写问卷参与调查，评估现代助听器在日常生活中对用户的益处。问卷包含20个项目，其中10个取自经过验证的国际量表（SSQ：言语、空间和听力质量量表，IOI-HA：助听器国际效果量表），另外10个是专门为此编制的。
共收回664份有效问卷，其中421名应答者是首次使用助听器的用户，243名应答者是之前使用过助听器的用户。本研究结果表明，对于本研究中测试的所有变量，现代助听器系统技术相对于上一代助听器在5%的水平上提供了显著的额外益处。
尽管由于众所周知的安慰剂效应，用户益处方面的增益量可能被高估，但明显的净效应是显而易见的。未发现助听器益处水平与可能的影响因素之间的相关性，这些因素如年龄、性别、受试者自己的助听器、使用时长或听力损失情况。
