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).
对不起，您的听力再也回不到17岁的时候。我们出生时大约有12000个听毛细胞，而这些听毛细胞会因为噪音、耳毒性药物、衰老等原因而死去，再也找不回来了。助听器和其他声音放大器虽然很棒，并且一直都在进步，但它们只是在最大程度地尝试弥补失去的听力（类似于假肢）。这也是为什么我们需要始终保护听力的原因。
