what is jet noise

Jet noise refers to the sound produced by the exhaust of a jet engine. It is characterized by a loud, high-pitched noise that is often heard when an airplane takes off or lands. The noise is caused by the high-speed exhaust gases exiting the engine and interacting with the surrounding air. Jet noise can be a significant source of noise pollution, particularly in areas near airports or military bases where there is a high volume of air traffic. Efforts are underway to develop quieter jet engines to reduce the impact of jet noise on communities
