How do you describe the tympanic membrane?
The tympanic membrane is also called the eardrum. It separates the outer ear from the middle ear. … The middle ear bones then transfer the vibrating signals to the inner ear.

The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.
