Fortunately, technologic improvements such as these have vastly increased acceptability: miniaturization, cosmetic improvements, and increased amplification ability for modest hearing losses earlier thought unaidable. The cochlear implant, approved by the FDA in 1984, is a major breakthrough for adults with profound hearing losses who are unable to be helped by conventional hearing aids.
幸运的是,诸如此类的技术进步极大地提高了(产品的)可接受性:小型化、外观改进,以及对早期被认为无法治疗的轻度听力损失增强了放大能力。1984年获美国食品药品监督管理局(FDA)批准的人工耳蜗,对于那些无法借助传统助听器得到帮助的重度听力损失成年人来说是一项重大突破。
