HOW DOES THE EAR RECEIVE INTERPRET SOUND?
you know how the sound is produced, but you still need to find out how the ear RECEIVES and interprets it!
There are three main sections of the ear - the outer ear, The middle ear, the inner ear.

The ear receives and interprets sound due to the functions of certain parts of the ear.
1. The Pinna which is the outer section of the ear collects the sound vibrations.
2. The vibrations are then directed by the ear canal towards the ear drum.
3. The sound vibrations cause the ear drum to vibrate, much like the skin of a drum.
4. Then the Hammer, anvil and stirrup pass on the vibrations from the ear drum to the cochlea, another part of the ear.
5. The cochlea's job is to translate the vibrations into electrical signals or nerve impulses. The cilia which are located in the cochlea trigger this and also detect and interpret the frequency of the vibration, this is the pitch of the sound.
6. After this the nerve which is connected to the brain/ Auditory, takes the electrical signals from the cochlea to the brain, and interprets them, this lets you know what you are hearing and also handles the sound.
There are also Semi Circular Canals which help you to balance, however these do not take part in the process of the ear interpreting and receiving sound.

The human ear can only respond to sound vibrations which are between 20Hz and 20kHz, usually elderly people have a smaller range of pitch that they can here due to the cilia which detect frequency being damaged or worn away from use.
