According to the tympanic membrane we can say that:

• It is located in the middle ear and when sounds reach it they cause to vibrate sending frequencies to the tiny bones of the middle ear (malleus, incus and stapes).

• It is located in the external ear when sounds reach it they send electromagnetic waves to be seen.

• All of the above.
