Question

Quizplus · Accepted Answer

The external acoustic meatus, also known as the ear canal, is a tube-like structure that delivers sound waves to the tympanic membrane (eardrum). The pinna (outer ear) helps funnel sound waves into the ear canal. The auditory tube is responsible for equalizing pressure between the middle ear and throat, and does not directly deliver sound waves to the eardrum.
