Sound Waves are Converted into Mechanical Movements by The

Question

Sound waves are converted into mechanical movements by the
A) auditory ossicles.
B) cochlea.
C) oval window.
D) round window.
E) tympanic membrane.

Accepted Answer

Sound waves first enter the ear canal and reach the tympanic membrane (eardrum). The tympanic membrane then vibrates and these mechanical movements are transmitted to the ossicles (3 tiny bones in the middle ear). Therefore, choice E is the correct answer as the tympanic membrane converts sound waves into mechanical movements.
