Colin Hansen

Emeritus Professor
University of Adelaide

After spending my entire working life teaching, researching and consulting in engineering noise control and active control, I am now retired from teaching and university administration but I am continuing to write books and software on engineering noise control, and I am also undertaking some research on wind farm noise.


Prof Hansen has been working in the field of noise and vibration for 40 years, first as a PhD student, then as a consultant in the USA (four years) and Australia (three years), and finally as an academic at The University of Adelaide, where he has been since 1986. During his career he has been responsible for over 100 consulting projects in noise and vibration control. He currently holds an Honorary Emeritus Professor position in the School of Mechanical Engineering where he is working on a number of acoustics related research projects, a new undergraduate textbook on engineering noise control, and consulting to an acoustics materials manufacturer.

He has authored or co-authored 13 books, edited two books, contributed seven chapters to various books and co-authored or authored over 300 papers in international journals and conference proceedings on acoustics and vibration. He is also a member of the editorial boards of two international acoustics and vibration journals. His research work in the past has been focused mainly on active noise and vibration control and now also includes the generation, impact and control of wind farm noise, which he has been working on since 2010. In 2012 he received a 3-year grant from The Australian Research Council to investigate the impact of wind farm noise on rural communities and in 2015 he was a CI in a group who received a 5-year grant from the Australian National Health and Medical Research Council to investigate the effects of wind farm noise on sleep.

Prof Hansen has co-developed a suite of noise control software (ENC) based on his Engineering Noise Control textbook, and this has more than 100 users worldwide. He has also published papers on sound transmission and sound radiation control, and papers on optimization problems including the optimization of passive noise control treatment for launch vehicles and the optimization of the shape of horns to achieve a specified sound field distribution and frequency response for use in cinemas. He has been an invited plenary keynote speaker at 14 International conferences (1995, 1996, 1997, 1998, 1999, 2003, 2004, 2007, 2009, 2012, 2015).

Prof Hansen served for two years (2000-2002) as President of the International Institute of Acoustics and Vibration (IIAV) and has also served in a number of other executive positions in the same organization since 1997. He is an Honorary Fellow of IIAV, a Fellow of the Australian Acoustical Society and a Fellow of Engineers Australia. He was the recipient of two Erskine Fellowships to spend 4 months in 2008 and 4 months in 2010 at The University of Canterbury in New Zealand.

In 2009 he was awarded the Rayleigh Medal by the British institute of Acoustics for outstanding contributions to acoustics. In 2013 he was awarded the A.G.M. Michell medal by Engineers Australia for outstanding service to the discipline of Mechanical Engineering and in 2014 he was awarded the Rossing Prize in Acoustics Education by the Acoustical Society of America.
