Active Noise Control at UWA - a Brief Review of the Acoustical Understanding and Practical Application of ANC Systems

The design, analysis and realization of Active Noise Control (ANC) systems have been challenges to acoustical and control communities over the last two decades. It is largely due to the effort in the acoustical community and to advances in digital signal processing technologies that significant progress has been made in this field. As part of this international quest in advancing ANC technology, researchers at the University of Western Australia (UWA) have focused on (1) applying an understanding of acoustical systems to the design of ANC systems and (2) the development of practical ANC systems for the Western Australian mining, shipbuilding and building industries. This paper presents a brief review of the contribution to these two areas by the UWA team including the results obtained from several practical applications.
