1) Our ear work on the frequency of sound. We can hear sound with in a frequency range of around 20hz- 20,000hz. Our ear has 3 parts - outer ear, middle ear and inner ear. Now outer ear has 3 sections first is pinna. Pinna is the visible part of the ear on the outside of our head.ear canal or auditory canal is second part of outer ear it help sound to travel inside our ear. Tympanic membrane is third section . It is a thin sheet that vibrates when sound hit it. Middle ear includes tympanic cavity and 3 ossicles. Oval window is a membrane covered opening that leads from the middle ear to the vestibule of the inner ear.
