Tympanic Membrane
The external auditory meatus and the external acoustic meatus are two names for the same structure.
The external auditory aperture is present in fetal pigs. This organ is the eventual opening for the auditory lobes in adult pigs.
The external auditory meatus is the ear canal that allows sound waves to pass from the external environment to the tympanic membrane (ear drum).
The tympanum (or eardrum) separates the external auditory meatus from the middle ear.
The auditory canal connects the outer ear to the tympanic membrane.
The fine hairs in the external auditory canal help to trap and prevent debris, such as dust and particles, from entering the ear. This helps to keep the ear clean and prevent blockages. The tiny wax-producing glands in the external auditory canal secrete earwax (cerumen) which helps to lubricate and protect the ear canal from infection and irritation.
The external ear is a cartilaginous structure, covered by thin skin. Elastic cartilage

It is located on temporal side of the skull and it is where sounds enters the human ear leading to the tympanic membrane. It is sometimes referred to as the extermal auditory canal.
