If you listen to a rock band at 130 dB, it may cause irreversible hearing damage. In contrast, tasting a boiling hot soup may burn your tongue but does not cause permanent damage. How can you explain this difference?
What will be an ideal response?
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.
