How loud are aircraft engines?
Aircraft engines are the major source of noise and can exceed 140 decibels (dB) during takeoff.
How much noise does an aircraft make?
A study of noise on Airbus A321 aircraft reported levels of 60-65 decibels (dBA) before takeoff; 80-85 dBA during flight; and 75-80 dBA during landing. The outside of aircraft engines (around 140 dB at takeoff) and conditions on other aircraft may have higher or lower noise levels.
What is the frequency of airplane noise?
The normal audible frequency for young adults is 20 Hz to 20,000 Hz. Community noise, including aircraft and motor vehicles, typically ranges between 50 Hz and 5,000 Hz.

What kind of noise does a propeller make?
In the case of a propeller aircraft engine, a propeller is attached to the end of the crank shaft to effectively pull it through the air. Large propeller aircraft are powered by turbo shaft engines which are very similar to jet engines. The source of noise in a propeller aircraft is the propeller itself as well as the engine exhaust.
