Profile

Trevor Cox carries out research, teaching and commercial activities in acoustics. He currently teaches courses in digital signal processing and room acoustics at degree and masters level, and supervises many project student. He is an EPSRC Senior Media Fellow and president-elect of the Institute of Acoustics.

Prof Cox carries out research in performance room acoustics, investigating how room conditions can be improved for good speech communication, and quality music production and reproduction. He has or is principal investigator on five EPSRC projects concerned with room acoustics. The results from GR/L13124 fed directly into Audio Engineering Society standard information document AES-4id-2001, the first standard on the measurement of surface diffusion. GR/L34396 developed an understanding of a new sound absorbing mechanism. GR/N39685 concerned room acoustic active diffusers.

Prof Cox is probably best known for his work concerning surface diffusers and has authored a text book on acoustic treatments. He pioneered the concept of optimised diffusers to help solve the dilemma of getting correct visual and acoustic design. His designs can be found in listening rooms (Sony M1, New York), cinemas (Cinema, Seattle) and concert halls (Hummingbird Centre, Toronto). He worked as a consultant for the world’s largest manufacturer of diffusing products, RPG Diffusor Systems Inc for over a decade. Prof Cox serves as an acoustic expert for international standard organizations, he is the UK expert on the ISO Working Group WG25. These are concerned with measures for diffusion/scattering.

Prof Cox has also used artificial intelligence means to model objective and subjective acoustics, investigate the socio-economic effects of hearing loss on the elderly and the use of arrays of DML loudspeakers. He has an interest in subjective testing, both qualitative and quantitative. He was investigator on a project concerning sustainability and the 24 hour city, and was the instigator and Director of the EPSRC Ideas Factory on Noise. Other perceptual work includes looking at product sound quality testing for the DTI and running a mass participation website to find the worst sound in the world.

He has published numerous international refereed journal articles and conference articles. Prof Cox is Associate Editor for room acoustics for the international journal Acustica united with Acta Acustica. He is a member of the Institute of Acoustics and the Audio Engineering Society.

Professor Trevor Cox was awarded the prestigious Tyndall Award by the Institute of Acoustics. The Tyndall Medal is awarded bi-annually to a citizen of the UK, preferably under the age of 40, for achievement and services in the field of acoustics.

Trevor Cox was a finalist at Famelab, a pop-idol style competition to find science communicators for television. Trevor carries out many projects concerned with communicating science and engineering to the public. He has been involved in EPSRC projects to produce resources for teaching acoustics for GCSE and AS/A level students, and holder of an EPSRC stages award to promote engineering. He is resident scientist on BBC Radio Manchester and has presented a nine documentaries for BBC radio 4 and World Service. Hee has been raising money for comic relief by running a silly science web experiment about whoopee cushions sounds. www.soundsfunny.org. and also looking into scary screams for the Manchester science festival
