Sound travels as waves. Your outer ear collects them and guides them down the ear canal.
The waves make your eardrum vibrate. Three tiny bones pass those vibrations into the fluid-filled cochlea.
Inside, movement bends tiny hairs on sensory cells, helping turn vibrations into electrical signals. The auditory nerve carries these signals to your brain, which interprets them as sound.
