What parts of the ear have a gaseous medium?
The parts of the ear that have a gaseous medium include the external auditory canal and the middle ear. The external auditory canal, which extends from the outer ear to the eardrum, is filled with air. The middle ear, located behind the eardrum, contains air and is connected to the nasal cavity via the Eustachian tube, which helps equalize pressure. In contrast, the inner ear is filled with fluid.

What is a fact on hearing?
The outer ear directs sound vibrations through the auditory canal to the eardrum, which is stretched across the end of the auditory canal and which transmits sound vibrations to the middle ear. There a chain of three tiny bones conducts the vibrations to the inner ear. Fluid inside the cochlea of the inner ear stimulates sensory hairs; these in turn initiate the nerve impulses that travel along the auditory nerve to the brain.
