Our ears are made up of three parts: the outer ear, middle ear, and inner ear. When our ears pop, the sensation comes from the Eustachian tube. The air pressure balance between the middle ear and outside environment is critical for our ears to properly function. When the pressure in the middle ear is lower than the outside air pressure, that can create negative pressure. For those experiencing persistent ear pressure issues, an ear, nose, and throat doctor can evaluate them for Eustachian tube dysfunction.
