摘要：
A discussion regarding the common noise sources and its corresponding diagnostic techniques through several case studies is presented. The source of such an aircraft interior noise is due to the effect of several aerodynamic, noise and vibration which include the turbulent boundary layer over the fuselage surface, the environmental control system (ECS) or simply the air-conditioning, engines, hydraulic motors, drive airframe components, on-board equipment and special mission equipment for military aircraft. Through the case studies, it can be seen that treating the source is more cost-effective and weight-effective approach in addressing such problems in noise and vibration.
