Conventional hearing aids have a number of limitations inherent to amplifying sound in the narrow confines of the external auditory canal. Disadvantages include acoustic feedback, poor fidelity, and the stigmata of aging. Since 1986, Michigan Ear Institute and Smith and Nephew Richards Company have been investigating the feasibility of a new device that converts sound to an electromagnetic field. The efficacy and safety of electromagnetic-induced hearing was sufficient enough to have the Federal Food and Drug Administration approve a pilot study of ten patients with a sensorineural hearing loss in whom a target magnet is implanted beneath the tympanic membrane. A status report of this study and a review of our preceeding investigations are presented in this article.
传统助听器在狭窄的外耳道内放大声音存在一些固有的局限性。缺点包括声学反馈、保真度差以及衰老的特征。自1986年以来，密歇根耳科研究所与史赛克公司一直在研究一种将声音转换为电磁场的新设备的可行性。电磁诱导听力的有效性和安全性足以让美国食品药品监督管理局批准一项针对10名感音神经性听力损失患者的试点研究，这些患者的鼓膜下方植入了一个目标磁铁。本文介绍了这项研究的现状报告以及对我们之前调查的回顾。
