The pinna and outer ear collect sound waves. They send these sound waves to the eardrum.
Sound travels in waves. Short wavelengths are high pitched and long are low pitched. Great amplitude waves are loud sounds whereas small amplitude waves awe soft sounds.
The eardrum is a tight membrane. It vibrates sound waves.👂
The hammer, anvil and stirrup make up the middle ear. They send the vibrations down to the cochlea, amplifying them.
The cochlear is located in the inner ear. Sound vibrations make the cochlear's membrane vibrate, and the fluid inside of it is also effected.
This in turn makes the hairs lining the basilar membrane bend and move. This relays the impulse to the auditory nerve
The auditory nerve carries the signal to the auditory cortex in the temporal lobe. Through this process we can hear a wide array of sounds, You may license this video royalty free by contacting us at Many of us take for granted a very extraordinary ogan... our ears. To und...
