双耳聆听有助于聆听与语言的发展。
听力学会建议：双耳配戴助听器
众所周知，音乐和言语的立体声效果更佳。双耳听力受损的话，双耳配戴助听器会产生立体声的效果。如果您双耳听力受损，建议双耳选配助听器。相比单耳配戴，双耳配戴有以下好处:
双耳聆听优势
对声音准确定位
单耳配藏者听到背后汽车的声音，却不能判断汽车是从哪一侧开过来，这是件危险的事情:而双耳配戴就不会出现这样的情况。
保护剩余听力
仅仅单耳配戴，会过度依赖配戴助听器的一侧耳；对侧耳长期得不到锻炼，残余听力会逐步丧失，这就是医学中的“听觉剥夺”现象
更容易听清言语的内容
双耳配戴可以消除“头影效应”，减少头部对高频声音的的阻碍，更容易听清和分辨言语的内容。
聆听过程更轻松不费力
单耳配戴者听小的声音比较费力，而双耳累加则可以提高声音的总体响度，听小声也不费力
在噪音环境里更容易听清
双耳配戴有“静噪作用”，可以很好的抑制背景噪音，提高信噪比
声音更立体
双耳聆听会产生立体声效果，您听到的言语声更自然，音乐声更美妙
双耳听力都有损失，却放大其中一只，像双近视却只做戴一片眼镜样低效。
