What Makes Your Ears Ring?

The video explains tinnitus, a condition affecting 20% of people, often caused by exposure to loud noises. Tinnitus is a sign of hearing loss, where sound waves are converted into electrical signals for the brain. Hair cells in the cochlea vibrate with sound frequencies, but loud sounds can damage these cells, leading to tinnitus. Damaged hair cells leak electrical impulses, causing the brain to perceive noise even when there is none. While hair cells can recover, repeated damage can lead to permanent tinnitus.
