Answer Details
The part of the ear which equalizes air pressure on either side of the eardrum is the Eustachian tube.
The Eustachian tube connects the middle ear to the back of the throat, allowing air to flow in and out of the middle ear, which helps to equalize the pressure on either side of the eardrum. When there is a pressure difference, such as during changes in altitude, the Eustachian tube opens briefly to equalize the pressure and prevent discomfort or damage to the eardrum. In some cases, the Eustachian tube may become blocked, leading to ear pain or difficulty hearing, and this can be addressed through various treatments, such as nasal sprays or surgery.
