It is harder to hear a sound made farther away. It is also harder to hear a sound when other sounds are louder.
Sounds pass into the ear. They make the eardrum vibrate. That makes tiny bones in the ear move. The bones move a small tube shaped like a snail shell, called the cochlea. Inside the cochlea is a fluid, which moves tiny hairs that send signals to the brain.
