Why do Ears pop?
Ears are the primary organ for hearing. Without ears, it would be impossible for someone to audibly hear what another is saying. The ears are designed to function as the sound system of the body. It is in its anatomical position and structure to be able to let an individual hear and listen to any kinds of sound. The way the ears are able to catch and transmit is quite easy to understand. Specific parts have corresponding functions for sound to be heard. As the ears catch sound, it transmits the sound towards the brain for interpretation and the brain sends a response to the sound being transmitted. The two-way communication between the ears and the brain is important for sound to be heard and interpreted.
The air in the atmosphere highly affects the pressure of air within the ear. As the ear is divided into three parts, the inner and middle ear should have equal amounts of pressure for an individual to be in comfort. However, when pressure changes occur, either going up in flight or going down as in landing, the ears tend to rectify any felt discomfort. In going up in flight, the pressure of air decreases in the atmosphere. This creates an increased pressure within the ear. To rectify this imbalance, the ear tends to pop to equalize the pressure from within and outside the ear. Opening the mouth is the most common method of popping the ear. On the other hand, the air pressure in the atmosphere increases while the pressure within the ear decreases during landing. Because of this, the ears also have the tendency to pop to equalize both pressures.
It is important therefore that the pressure within the ear is maintained at a balance with the atmospheric pressure.
