听力损失很严重,戴助听器还管用吗?

外内要通过内因起作用,助听器在整个听觉的过程中是外因,患者本身的听力是内因。若患者的听力已经是极重度的听力损失,即使佩戴助听器,也不会有太大效果。

助听器的工作原理是什么?

助听器是通过机身上的麦克风接收声音,内部的放大电路将声音放大,再利用听障者的残余听力,把声音送到大脑听觉中枢,从而感觉到声音。

助听器的放大电路已经达到智能化水平(相当于一台笔记本电脑),它对声音的处理是多维度智能化的。比如,患者是一个高频为主的听力损失,放大电路则主要集中在高频听力。

听力彻底“垮掉”了,戴助听器还有用吗?

很多老年人出现小声听不见、大声受不了的状况,这种现象在医学上叫做重振。助听器可以根据不同的声音给予不同的放大,是一种压缩的放大。

另外,助听器还能自动感知周围环境的变化,对助听器参数进行调整。好的助听器还能跟蓝牙技术相结合,把远程的声音用远程麦克风接收下来,通过蓝牙直接送入患者的耳道。
