Hearing Protection for Aviation

Some do, especially in louder piston, open, or vintage cockpits or on long cross-country flights. Foam plugs worn under a headset add protection and reduce fatigue, but they also muffle the radio, so pilots flying solo usually rely on the headset alone and reserve doubling up for passengers or extreme noise.

For foam ear plugs, look for a noise reduction rating in the high 20s to low 30s in decibels, near the top of what passive plugs achieve. That is plenty for passengers and ground crew. Pilots who need to hear the radio should choose a communications headset rather than judging protection by NRR alone.

For non-communicating passengers and ground crew, well-fitted foam plugs usually attenuate more than earmuffs and pack smaller. For the pilot flying, neither beats a communications headset, which protects hearing while letting you hear the radio and intercom. Many pilots combine plugs under a headset for the loudest aircraft.

Yes, but not by simply adding the two ratings together. Wearing foam plugs under a headset or earmuff typically adds about five decibels over the higher of the two ratings. It is a real, useful gain for long or especially loud flights, though it does reduce how clearly you hear radio and intercom audio.

Cockpit noise in a typical piston single or twin commonly runs from about 80 to over 100 decibels, depending on the aircraft, power setting, and whether a door or window is open. That range causes cumulative, permanent hearing damage with repeated exposure, which is why hearing protection on every flight matters.

Yes. Passengers are exposed to the same cockpit noise as the pilot, and most ride without a headset. A pair of foam ear plugs is an inexpensive way to protect a passenger's hearing and make the flight more comfortable, and it is smart to keep a few spare pairs in a seat pocket for guests.
