1.Sound transfers into the ear canal and causes the eardrum to move

2.The eardrum will vibrate with vibrates with the different sounds

3.These sound vibrations make their way through the ossicles to the cochle

4.Sound vibrations make the fluid in the cochlea travel like ocean waves

5.Movement of fluid in turn makes the hair cells The auditory nerve picks up any neural signals created by the hair cells. Hair cells at one end of the cochlea transfer low pitch sound information and hair cells at the opposite end transfer high pitch sound information.

6.The auditory nerve moves signals to the brain where they are then translated into recognizable and meaningful sounds. It is the brain that “hears”.

Explain how human ear works??

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

✰✰ ANSWER ✰✰

Human Ear is divided into three parts : -

★Outer Ear

★Middle Ear

★Inner Ear

_______________________

Outer Ear : -

It consists of pinna which collects sounds from the surroundings..Then there is auditary canal from where sound passes and strikes a membrane called as Eardrum or Tympanic Membrane..

Middle Ear : -

It consists of three bones shaped as hammer,anvil and stirrup.These bones receives the vibrations from the Eardrum and vibrates and amplify them and then transmit it to the Inner Ear..

Inner Ear : -

It consists of cochlea and auditary nerve .Here cochlea converts pressure vibrations/variations into electrical signals and these electrical signals are sent to the brain via auditary nerve where they are interprected...
