Answer 1

The most common cause of permanent hearing loss is due to the tiny hairs in the **cochlea** being damaged or destroyed, often by loud sounds. These tiny hair cells are essential for converting sound vibrations into electrical signals that the brain interprets as sound. Once these hair cells are damaged, they do not regenerate, leading to permanent hearing loss.
