Dr. K Viswanathan (Vishy) presented on aircraft noise production and mitigation to a crowded room of AE students and faculty. Dr. Vishy covered topics spanning commercial and military aircraft, emphasizing specific aircraft and engine components that generate noise. He explained some of the methods utilized at The Boeing Company for measuring noise and mitigating it as well. The top example presented was the beveling of a jet engine nozzle to direct the propagation of noise away from servicemen on the deck of an aircraft carrier. Dr. Vishy identified needed technological breakthroughs and studies to win this noisy battle.
