Sorry,but you’ll never hear again like you did when you were 17.You have about 12,000 hair cells when you’re born and each time one of them dies from harmful noise,drugs(ototoxins),aging,etc,you’ll never get them back.Hearing aids and sound amplifiers are great and are always improving,but they’re the equivalent of a prosthetic limb:they’re designed to maximize the hearing you have left(one more reason why you should always protect your hearing).
對不起，您的聽力再也回不到17歲的時候。我們出生時大約有12000個聽毛細胞，而這些聽毛細胞會因為噪音、耳毒性藥物、衰老等原因而死去，再也找不回來了。助聽器和其他聲音放大器雖然很棒，并且一直都在進步，但它們只是在最大程度地嘗試彌補失去的聽力（類似于假肢）。這也是為什么我們需要始終保護聽力的原因。
