单侧听力下降可选单耳助听器 - 上海助听器-静安虹口助听器-5折起上海助听器折扣店

一只耳朵的听力已经下降,而另一只耳朵的听力正常,一般建议选配助听器进行听力辅助治疗。那么像这种症状,该选择双耳助听器还是单耳助听器呢?

如果患者双耳的听力都差,在个人经济条件允许的情况下至好选配双耳助听器。其音质自然清晰,饱满,更利于掩蔽耳鸣。一方面可以提高听力障碍患者在噪音环境下的言语辨别力,有利于声源定位,更容易区分不同方向的言语声。另一方面可以消除因头颅阻挡声音产生的头影效应、预防听觉剥夺现象(即双侧对称性听力受损者单耳选配助听器未助听耳间延长言语分辨率渐进性衰退的现象)、减低回响效应、提高声音响度、提高言语分辨率,,充分发挥听觉系统能力等作用。

需要注意的是,双耳选配助听器虽然有很多优点,但并非适用于所有听力障碍患者,例如单耳听力障碍患者或双耳配戴后言语分辨率反而比单侧好耳差者,不宜选配双耳助听器。如果听障者有听力长期不对称的现象,例如一只耳朵听力正常,另一只耳朵听力差,也可以考虑选择单耳助听器。在双耳戴上助听器后,听障者感觉堵耳效应严重,或两耳音调感受差别很大,或有其他疾病等多功能障碍时,也不宜选配双耳助听器。
