助听器主要有哪些种类?

助听器,可分为骨导助听器和气导助听器。骨导助听器仅适用于外耳道闭锁,或者长期多次中耳炎手术效果不佳的患者,是相对小众的助听产品。

市面上大多数的助听器都是气导助听器 ,气导助听器从外观上又可以分为盒式(别在衣领或胸前)、耳后式(挂在耳后)、定制式(按照耳廓形状制作)。


不同类型的助听器有何优缺点?

1、耳后式助听器

优点是个头相对较大,提供的放大能力也强,更适用于听力损失程度比较严重的人。

缺点是头发上的汗水容易使麦克风受潮,所以每年的7-8月份是耳后式助听器故障的高发期。


2、耳内式助听器

优点是适合听力损失的范围较宽,输出功率较大,佩戴简单美观

缺点是由于机身限制,受话器等电子元器件性能品质略差;体积小,容易丢失;容易被耳屎堵塞产生堵耳效应,佩戴者说话时有一种瓮声瓮气的感觉。
