Broadband cabin noise, which can greatly fatigue passengers in even the most finely appointed business aircraft, could be a thing of the past if a new system from Britain’s Ultra Electronics and Qinetiq makes it to market. Early next year the partners are expecting to flight test new-generation hybrid active/passive mounts positioned between the fuselage and cabin trim panels.
Noise is everywhere–annoying, tiring and sometimes painful. Since the early days of aviation, when a roaring, clattering engine sat on a wooden frame close to the pilot, and the wind whistled through the wire bracing like a banshee chorus, engineers have sought to make the process of manned flight less noisy. And they have succeeded, to a degree.
