原位助听器失真的定义是在耳道内测量到的失真，其刺激输入和助听器设置类似于助听器佩戴者在日常生活中所经历的那些。这项初步研究考察了原位失真与适当安装的当代助听器的益处之间的可能关系。对97个助听器配件进行了模拟现场失真测试，将其分为三个典型的听力环境：客厅、教室讲课和社交活动。测量方法包括互调、谐波和瞬时失真。受试者之间和受试者内部对数据的总体分析结果表明，在混响和嘈杂环境中，失真和收益之间存在显著关系，分别类似于课堂演讲和社交活动。尽管从绝对值来看，扭曲程度相当低，但仍能看到这一结果。分析还表明，现场谐波失真与惠益关系最密切，所测量的其他类型的失真对惠益预测没有额外贡献。我们认为，现场谐波失真的测量可能是助听器评估的一个有价值的补充。
In-situ hearing aid distortion is defined as distortion measured in the ear canal with stimulus inputs and hearing aid settings that are similar to those the hearing aid wearer will experience in daily life. This preliminary study examined possible relationships between in-situ distortion and benefit for appropriately fitted contemporary hearing aids. Simulated in-situ distortion was determined for 97 hearing aid fittings, divided among three typical listening environments: living room, classroom lecture, and social event. Measures included intermodulation, harmonic, and transient distortion. Overall results of between- and within-subject analyses of data suggested that there was a significant relationship between distortion and benefit in both reverberant and noisy environments similar to a classroom lecture and a social event, respectively. This outcome was seen despite the fact that distortion was quite low in absolute terms. Analyses also suggested that in-situ harmonic distortion was most closely related to benefit and that the other types of distortion measured did not make additional contributions to benefit prediction. We propose that measurements of in-situ harmonic distortion might be a valuable addition to hearing aid evaluations.
