选配合适的助听器能使耳聋患者的残余听力提高到接近正常人的水平。实际上选择助听器的电声性能指标是由耳聋患者听力损失情况来确定的。本文想通过对助听器电声性能指标测量方法的介绍,使读者从另一个侧面来了解这种特殊的电声放大系统的有关情况。
Selecting the right hearing aids increases the residual hearing loss in deaf patients to nearly normal levels. In fact, the electro-acoustic performance of hearing aid is determined by hearing loss in deaf patients. This article wants to introduce the measurement method of electroacoustic performance of hearing aids to make readers understand the situation of this special electroacoustic amplification system from another aspect.
