The function of middle ear is-
Ans: A. Impedence matching(Ref: Dhingra's S'h/e p. 18; Tuli L't/e p. 35)The middle ear ossicles provide a pathway for sound to travel from the outer to the inner ear.Opposition to sound energy transfer is known as impedance.The ossicles exist to help overcome the effect of impedance by impedance matching, thus permitting more sound energy to be transmitted from the outer to the inner ear.
Impedence matching
Conveing sound energy into electric energy
Increase in intensity of sound
Helps in equilibrium
