Membran- is the medical terminology combining form meaning membrane.
This is an embryonic structure that will form the pharynx (throat) and the tympanic membrane (ear drum)

Mechanical energy in the form of sound waves is imparted onto the tympanic membrane. The sound waves cause the membrane to vibrate, which in turn transmits the vibrations through the middle ear to the inner ear, where they are converted into electrical signals for the brain to interpret as sound.
