Why are airplanes so loud inside?

A moving aircraft causes friction and turbulence, which triggers sound waves. Generally, the faster the aircraft is flying, the more turbulence and friction will occur. When the aircraft's landing gear and flaps are used, more noise is made because more resistance is being created.

Take-off and landing are the loudest moments, when noise levels inside the cabin can reach 105 decibels (dB). At cruising altitudes, noise drops to around 85 dB, says Pamela Mason of the American Speech-Language-Hearing Association (ASHA). Long exposure to 85 dB can cause temporary hearing problems.

Airplane noise can be very annoying, especially if you live or work near an airport, and you should know that experiencing that noise constantly can be bad for your health. Some of the negative side effects include high blood pressure, increased risk of stroke and increased risk of heart attack.

The influence of atmospheric conditions Temperature, wind speed and direction, humidity, rain and cloud-cover all have a part to play in the way we hear aircraft noise. The reverberation of sound waves caused by the weather can make noises seem louder.

Over the past 50 years, aircraft have reduced their noise output by 75% and this progress continues. Today's aircraft entering service have on average, a noise footprint that is 30-50% that of the aircraft they are replacing thanks to new engine and airframe design and technology.

If the noise of flights passing overhead is unbearable and you're able to do some repairs on your home, you may also consider getting some noise-canceling curtains, insulating your windows and doors and filling in any sound gaps that may help quiet your environment.

Noise From Planes Can Damage Your Hearing Exposure to any noise louder than 85 decibels (dB) puts your ears at risk. In-flight the volume tends to hover right around 80-85 dB, however during takeoff and landing it can get even louder.

Besides skinny seats, slim lavatories and overstuffed overhead bins, here's another reason to loathe the back of the airplane: It's noisier than the front. The noise inside an airplane is a choice airlines and airplane manufacturers make.

During the day, when the air is warmer than the ground, noise energy from an airplane staying in the air, so while you can still hear it, it seems quieter. Conversely, at night, when the ground is warmer than the air, the noise is drawn down, making it seem louder.

Jet airliners, on the inside, are loudest in the last few rows at the rear. Outside, right at the engine exhausts, but you're in serious danger from the engine if you're anywhere near that. Most of the noise goes backwards away from the plane.

For most commercial airplanes, the seats closest to the front of the plane are the quietest. And although it's not always possible to get a front row seat, anything in front of the wing is preferable to seating behind the wing. The loudest row is just behind the wing where the engines are located.

Yes, travelers have the right to quiet, but it's an implied right, and one enforced by the good manners of your fellow passengers and guests.

How to Know If You Live Under a Flight Path. Before you rent or buy a new home, you can check out a few websites and apps to find out if you live under a flight path. With FlightStats you can track flights by airport, whereas FlightAware Flight Tracker clues you into private planes as well.

In fact, people exposed to airplane levels as low as 45 decibels were more likely to sleep less than 7 hours per night. That noise level is a little more than being in a library and a little less than a typical conversation in your home.

On an overcast day, the sound that normally goes up hits the cloud layer, which has a temperature differential and visible water vapor, and reflects back to the ground, thus increasing the audible sound at the ground.
