“impedances”
A mechanical factor that determines the amount of sound energy that is absorbed or reflected at the eardrum: Auditory impedance is also related to the loss of transmission of sounds to the middle ear and the cochlea (part of the inner ear that converts mechanical energy, or vibrations, into nerve impulses sent to the brain).
