Answer:
The statement is true.
Step-by-step explanation:
The middle ear transmits sound energy from the eardrum to the inner ear, carrying out an adaptation of impedances between an aerial medium and a liquid medium. If the vibrations of the air were applied directly to the fluids of the inner ear, the major of acoustic energy would be lost by reflection at the air-fluid interface. The middle ear is a pressure amplifier. In this way, the acoustic energy available in the air environment is "recovered" and the amplitude of the mechanical-acoustic stimuli in the inner ear is increased.
