As the variety of nerve endings decreases, so does your hearing. There is no chance to bring back life to dead nerve ends; the damage is long-term. The longer you are revealed to a loud sound, the more destructive it might be. Additionally, the closer you are to the source of intense sound, the more damaging it is.
