What is Noise Reduction with Blast Nozzles about?

Jet engine noise suppression has become a major area of research due to noise regulations. There are three main sources of aircraft noise: aerodynamic, engine/mechanical, and systems noise. Jet noise from commercial aircraft engines comes from fan/compressor noise and jet mixing noise, which is difficult to control. Chevron mixers installed on engine exhausts have successfully reduced jet noise by up to 4 decibels by enhancing mixing between air streams. Experimental aeroacoustics research uses techniques l
