Although individual aircraft has become quieter over the past 30 years but flight frequencies have increased. High speedy supersonic aircrafts are also using for military purposes. This paper focuses on the review of various methods employed in the past to reduce the jet noise as also the future expected methodologies hence the subject deals with sources, causes of noise and its propagation with a solution to prevent. Though it is a vast field in aviation sector, this topic is discussed in brief.
