Abstract

This paper describes the analysis and simulation of a simple sound cancellation system consisting of a single point primary sound source and two cancelling sources. Conditions for the global sound attenuation along multiple axis in the system are derived and system behaviour and cancellation effects, studied through computer simulations. This study is aimed at understanding the physics of more complex active noise control systems (ANCS) consisting of higher number of secondary sources and error sensors in free field. Results provide a useful insight into ANCS performance and can therefore be used as a valuable reference point when studying and analysing the free field operation of a more complex, multi-canceller ANCS.
