Active Control of Noise and Vibration

Integrating active control of both sound and vibration, this comprehensive two-volume set combines coverage of fundamental principles with the most recent theoretical and practical developments. The authors explain how to design and implement successful active control systems in practice and detail the pitfalls one must avoid to ensure a reliable and stable system. Extensively revised, updated, and expanded throughout, the second edition reflects the advances that have been made in algorithms, DSP hardware, and applications since the publication of the first edition.

Colin Hansen is professor emeritus in the School of Mechanical Engineering at the University of Adelaide. He established the ANVC group at the university in 1987 and led the group until his retirement at the end of 2011. The group is internationally recognized for its extensive contributions to the advancement of scientific knowledge in many aspects of active noise and vibration control. In 2012 he was made the 15th honorary fellow of the International Institute of Acoustics and Vibration (IIAV) in recognition of his "outstanding contributions to scientific knowledge in acoustics, noise and vibration" and in 2009 was awarded the Rayleigh Medal by the British Institute of Acoustics for "outstanding contributions to acoustics". Scott Snyder is currently pro vice-chancellor, strategy and planning, at Charles Darwin University (CDU). He has also been the Executive Director, Corporate Services and an Executive Dean at that institution. Prior to moving to CDU, Snyder was a member of academic staff in the School of Mechanical Engineering at the University of Adelaide, and later head of IT Services at that organization. His Ph.D. was in the area of active noise and vibration control and he spent a number of years undertaking further research on ANVC in Japan and at the University of Adelaide prior to being appointed to Academic Staff. Xiaojun Qiu is a professor in acoustics and signal processing and head of the Institute of Acoustics, Nanjing University. He worked with Colin Hansen in the School of Mechanical Engineering at the University of Adelaide, Australia, as a research fellow from 1997 to 2002. He is a member of the Audio Engineering Society and the International Institute of Acoustics and Vibration. He has authored and co-authored two books and more than 250 technical papers, and holds more than 70 patents on audio acoustics and audio signal processing. Laura Brooks was awarded a bachelor of mechanical engineering with first class honours in 2003 and a PhD in mechanical engineering in 2008, both from the University of Adelaide. She was selected by Engineers Australia for inclusion in the list of Australia's Most Inspiring Young Engineers in 2005 and was awarded the 2006 Fulbright Postgraduate Award in Engineering, enabling her to spend two years as a visiting scholar at the Scripps Institution of Oceanography in the United States. From 2008 through 2009 Laura worked as a postdoctoral fellow at Victoria University in Wellington, New Zealand. She was a lecturer in the School of Mechanical Engineering at the University of Adelaide from 2010 through 2012, and currently retains an adjunct position with the university. Her research interests span a broad range of fields including aeroacoustics, ocean acoustics, seismic noise, vibrations, active control, signal processing and engineering education. Danielle Moreau is a postdoctoral research associate at the School of Mechanical Engineering at the University of Adelaide. She completed her PhD on virtual sensing methods for active noise control at the University of Adelaide in 2010 and received a University Postdoctoral Research Medal for her PhD research. In her current role as research associate, the focus of Dr Moreau's work is on the understanding and control of flow-induced noise. Dr Moreau has over 20 publications in leading outlets and has also been invited to give seminars to research groups at Tokyo Metropolitan University (Tokyo, Japan), Stanford University (California, United States) and the National Energy Renewable Energy Laboratory (Colorado, United States).
