Active Exhaust Silencing Systen For the Management of Auxillary Power Unit Sound Signatures

Abstract

We propose a system for the active cancellation of exhaust sound power where the desired outcome is a compact and lightweight solution to reduce exterior noise levels to inaudible operation at 20 meters. We have identified two challenges in developing this solution. The first is the integration of COTS technology to provide the signal processing for the active system, and the second is the development of a novel noise source and sensors which can withstand the extreme environment within a vehicle exhaust.
