This study investigated the potential and limitations of a self-fit hearing aid. This can be used in the "developing" world or in countries with large distances between the hearing-impaired subjects and the professional. It contains an on-board tone generator for in situ user-controlled, automated audiometry, and other tests for hearing aid fitting. Twenty subjects with mild hearing losses were involved. In situ audiometry showed a test-retest reliability (SD <3.7 dB) that compared well with the precision of diagnostic audiometry using headphones. There was good correspondence (SD <5.2 dB) with traditional pure-tone audiometry. In situ loudness scaling yielded important information about suprathreshold perception, which will have an added value for the selection of compression and the selection of maximum power output to be allowed in hearing aids.
本研究调查了一种自适配助听器的潜力和局限性。该助听器可用于“发展中”国家或听力受损者与专业人员距离较远的国家。它包含一个板载音调发生器，用于原位用户控制的自动听力测定以及其他助听器适配测试。二十名轻度听力损失的受试者参与了研究。原位听力测定显示重测信度（标准差<3.7 dB），与使用耳机的诊断听力测定的精度相当。与传统纯音听力测定有良好的一致性（标准差<5.2 dB）。原位响度标度得出了有关阈上感知的重要信息，这对于选择压缩和确定助听器允许的最大功率输出将具有附加价值。
