Hearing is one of the five senses. The ears are used for hearing (listening to) sounds. The noun form of hearing may also be used to refer to a meeting, usually one where the public is invited to come and help decide something.

Sometimes the phrase "I hear you." can be used to mean, "I understand." 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 our ear and make the eardrum vibrate, which makes the tiny bones inside. The bones vibrate 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.

Three canals next to the cochlea, in the inner ear, help us keep our balance. They let the brain know what movements the body is making. Ballet dancers need excellent balance.[1]
