Understanding Sound Waves: A Detailed Explanation

Sound is created when an object is hit and starts oscillatory motion, causing the object to vibrate at its natural frequency.
The vibrating object pushes against air molecules, compressing them and creating a sound wave that moves through the air.
The sound wave consists of compressions and rarefactions, regions of compressed and rarefied air respectively.
These compressions and rarefactions move radially outward in all directions until they reach someone's ear.
The air compressions enter the ear canal and hit the eardrum, causing it to vibrate at the same frequency as the sound wave.
The eardrum is connected to the hammer bone, which then vibrates and transfers the vibration to the anvil bone.
The anvil bone is connected to the stirrup bone, which is connected to the cochlea, a snail-shaped structure filled with fluid.
Inside the cochlea, there are tiny hairs called cilia that are sensitive to vibrations in the fluid.
Each cilia is sensitive to a different frequency, so the frequency of the sound wave is determined by which cilia are vibrating.
The cilia are connected to nerve endings that come together into a nerve bundle that goes to the brain.
The brain interprets the nerve signals as sound and turns it into something we can recognize.
Sound waves are actually compression waves in the air until they are interpreted by the brain as sound.
