Technologies for Aircraft Noise Reduction: A Review

Mojtaba Sadeghian, Mofid Gorji Bandpy

This article presents a review of current aircraft noises and technologies to reduce noise as well as an estimate of the technology’s readiness level. Aircraft noise remains the key inhibitor of the growth of air transportation and remains an acute environmental problem that requires advanced solutions. To deal with this problem, aircraft manufacturers and public establishments are engaged in research on technical and theoretical approaches for noise reduction concepts that should be applied to new aircraft. This review paper discusses a selection of enabling technologies and their implications on acoustics and noise and gives a perspective on future trends and new directions in aeroacoustics required to address the challenges.
