The middle ear consists of the tympanic membrane, the boundary between the outer and middle ear. Sound Gettingth through the ear canal to the eardrum, which creates tension, which in turn transferred the three ossicles located in the middle ear: hammer, anvil and stirrup. And they begin to vibrate. This vibration is transmitted to the inner ear organs.

The inner ear

The inner ear consists of preddvedence and snails. Both these bodies are bone formations in the form of tubes. Snail is also divided into three channels, which are filled with fluids. The ear is arranged in such a way that causes the vibration response of the stirrups and the fluctuations of these liquids. Then the sound waves are transmitted directly to the auditory analyzers, where the sounds are converted into nerves pulses. And as such, this information is transmitted to the brain, where they differentiate into pulses of different sounds.
