Video narration
How does a clap in the air become something you hear? When you clap, you set the air vibrating. Those tiny changes in air pressure travel to your ear, carrying the clap's pattern. The vibration enters the ear canal and makes your eardrum, a thin membrane, move back and forth. Your ear doesn't just receive the clap. It changes those air movements into signals your brain can read. Three tiny bones behind the eardrum pass the vibration along to the cochlea, a curled part of the inner ear. Inside it, tiny hair cells move with the vibration and turn that movement into nerve signals. The signals travel to your brain, which interprets them as the clap you recognize. So what made the clap something you hear? That's how you hear the clap: your ear turns vibration into nerve messages, and your brain makes sense of them.
