An atmospheric pressure adjustment apparatus is disclosed. The atmospheric pressure adjustment apparatus comprises: a speaker; a microphone; an earplug of which a main body is made of an elastic material so as to seal the external auditory meatus when the earplug is worn on the ear of a user, and which comprises an atmospheric pressure adjustment part penetrating the main body; and atmospheric pressure adjustment device for adjusting the fluid volume of the atmospheric pressure adjustment part; and a processor for outputting a sound through the speaker when the earplug is worn, measuring the air pressure difference between the middle ear internal atmospheric pressure and the external auditory meatus atmospheric pressure of the user on the basis of the strength of a received echo when the echo of the sound reflected from the eardrum of the user is received through the microphone, and adjusting the atmospheric pressure difference by moving the atmospheric pressure adjustment device according to the measured atmospheric pressure difference.
