The market share of the In-the-ear hearing aids in the United States of America, which increased more than 50% last year, points to a possible comparable development in the Federal Republic of Germany, where the 1983 quotas were below 4%. Those who are responsible for the supply of hearing aids should pay more attention to imparting more information on the technique, adaption and further aspects of In-the-ear hearing aids. After outlining the various forms of In-the-ear hearing aids (modular, custom-made, ear-channel apparatuses) initial experiences with In-the-ear hearing aids are reported together with technical points and questions of adaption. Our research results based on localisation tests, discrimination scores in quiet and noisy surroundings, and a questionnaire to compare In-the-ear with Behind-the-ear hearing aids, confirm the results communicated in other publications. Apart from the various positive aspects, which favour a more frequent use of In-the-ear hearing aids, their limitations are also pointed out and discussed.
去年在美国，入耳式助听器的市场份额增长超过50%，这表明在德意志联邦共和国可能会有类似的发展，该国1983年该类产品的配额低于4%。负责助听器供应的人员应更加注重提供有关入耳式助听器技术、适配及其他方面的更多信息。在概述了入耳式助听器的各种形式（模块化、定制、耳道式装置）之后，报告了使用入耳式助听器的初步体验以及技术要点和适配问题。我们基于定位测试、安静和嘈杂环境中的辨别分数以及一份比较入耳式和耳背式助听器的调查问卷得出的研究结果，证实了其他出版物中所传达的结果。除了有利于更频繁使用入耳式助听器的各种积极方面外，还指出并讨论了它们的局限性。
