You can wear hearing aids on an airplane.
Hearing aids are not prohibited from being carried or used on an airplane. They are small electronic devices used to help people with hearing impairments hear better. During the flight, passengers can wear hearing aids normally to better communicate with the crew, listen to various prompts and broadcast information during the flight, etc.
However, during the takeoff and landing of the aircraft, due to changes in air pressure, ear discomfort may occur. People wearing hearing aids may need to balance ear pressure by chewing gum, swallowing, etc. to relieve discomfort
