WAVES TO SIGNALS

YOUR EARS ARE RECEIVERS!
Our ears collect sound waves and turn them into electrical signals. These signals travel through the auditory nerve to the brain, which then interprets the vibrations as speech, music, or noise. Hearing is not just about catching air bumps. It is a full journey from the outside world into the busy control room inside your skull.
👂 DID YOU KNOW?
The curved outer part of your ear is called the pinna. Its shape helps funnel sound waves into the ear canal, like a satellite dish catching a signal from space!
