Hearing loss is one of the important health problems that the pilots encounter. Noise and barotrauma are the two important reasons that may lead to hearing loss in pilots.

Pilots need hearing protection because the sound levels within the cockpit can reach between 80 to 95 dB. Sounds at or below 70 dBA are generally considered safe.
Chewing is another practice that helps pilots to relieve ear popping. Just like yawning or swallowing liquids, chewing also stretches areas around the ears, equalizing the pressure inside the ear.
Again, FAA hearing standards allow the use of BOTH ears to pass, not just EACH ear. A pilot could be completely deaf in one ear and still meet FAA standards. This may present problems in the cockpit using an earpiece in one ear for radio communications and spoken voice for crew cockpit communications.
Chewing is another practice that helps pilots to relieve ear popping. Just like yawning or swallowing liquids, chewing also stretches areas around the ears, equalizing the pressure inside the ear. Chewing gum, gummy bears, and other chewy candies can help alleviate tension in the ears caused by altitude changes.
One of the most common risks associated with being a pilot is the physical and mental strain. Pilots must remain alert and focused for long periods of time, often in difficult circumstances. This can lead to fatigue and stress, both of which can have a negative impact on their performance and safety.
Perilymph fistulae (PLF) are rare and controversial disorders of the inner ear, mainly seen in Scuba divers and individuals with barotrauma such pilots and airline attendants. Their symptoms are similar to individuals with SCD, in that both can cause vertigo from pressure fluctuations.
It's all due to pressure changes. As the plane starts to lose height, the pressure in the air around you changes. Until the pressure inside the tubes behind your eardrum adapts, the pressure inside and outside your ear is different.
Mild symptoms of ear barotrauma usually last a few minutes. If they last longer, you may need treatment for an infection or another problem. Serious damage, such as a burst eardrum, may take a few months to heal. Sometimes you may need surgery to repair the eardrum or the opening into your middle ear.
Introduction. Changes in air pressure during flying can cause ear-drum pain and perforation, vertigo, and hearing loss. It has been estimated that 10% of adults and 22% of children might have changes to the ear drum after a flight, although perforation is rare. Symptoms usually resolve spontaneously.
“The ups and downs are constant, and we fly at all different times of the day,” Deitz says. “It's a stress on your body.” Takeoff and landing are the trickiest parts of a given flight, requiring all of a pilot's attention and mental energy. Heart rate increases during those windows, studies show.
