The ear is a special organ that helps you receive the sense of sound. Without your ears, you would have a harder time being able to locate the sounds found in the world that you experience every day.
In this project, you investigate just how sensitive your hearing really is.
HOW YOU HEAR
Hearing involves 3 separate areas of your ear.
The ear itself is like a giant microphone. It helps concentrate the sounds that you hear so that it can travel into the ear canal.
The middle ear is where the important actions occur. In the middle ear, a system of small bones help transfer the vibrations of sound to the inner ear, the actual part that helps process your sounds.
Each time you hear a noise, it comes as a different pitch. These sounds exists as waves and travel throughout the air. Even though we can't see sound waves with our eyes, these sound waves actually have different lengths and help make different notes! That's why Adele sounds like a god and Ke$ha sounds like a squealing pig.
Once the sound travels to the inner ear, your ears process the sound and send electrical signals to your brain to recognize what you hear.
