Question
How does a sound wave transfer energy to your ears?
Solution
-
Sound waves are created when an object vibrates. This vibration causes the surrounding air particles to vibrate as well.
-
These vibrations in the air particles create pressure waves that move through the air.
-
These pressure waves reach your ear and cause your eardrum to vibrate. The eardrum is a thin piece of skin that is tightly stretched across the end of the ear canal.
-
The vibrations of the eardrum are transferred to the three small bones in the middle ear: the hammer, anvil, and stirrup.
-
These bones amplify the vibrations and send them to the cochlea, a fluid-filled structure in the inner ear.
-
The vibrations cause the fluid in the cochlea to move, which moves tiny hair cells. The movement of these hair cells sends electrical signals to the brain.
-
The brain interprets these signals as sound. This is how a sound wave transfers energy to your ears and allows you to hear.
