Loud noise damages the hairs on the hair cells of the inner ear. When the hairs are exposed to too much noise, they wear down, lose their flexibility, and can fuse together. You cannot grow spare parts for your ears. However, the cells of a taste bud are completely replaced about every 10 days, so you need not worry about permanently losing your sense of taste when you burn your mouth eating overly hot food.
