Tim Mellow was educated at Boundary Oak School and Lancing College before obtaining a B.Sc. in Electrical Engineering and Electronics from the University of Dundee, Scotland, in 1985. A career as a Design engineer at BICC, Marconi, Thorn EMI, Racal, VTech, and Nokia followed. In 2011, he co-founded Mellow Acoustics Ltd with Philip Trevelyan to both provide an acoustical consultancy service and to develop high-end audio products. Tim takes a keen interest in music and plays the piano in his spare time. He has published many articles on audio and acoustics over the years, including 11 papers in the Journal of the Acoustical Society of America, mainly with Leo Kärkkäinen as co-author.

"Even to those that already own a copy of the 1954 edition, I would recommend acquiring a copy of the revision. It has sufficient new material and it is a pleasure to read to justify that cost. To those starting out in the fields of room acoustics or electro-acoustics or those wishing to extend their existing knowledge, it would be invaluable.very well worth the current list price."--Acoustics Bulletin, January/February 2013, Vol. 38, No 1, page 51 ".a modern expansion and re-working of Acoustics, the 1954 classic reference.updated throughout and focused on electroacoustics with the needs of a broad range of acoustics engineers and scientists in mind, this new book retains and expands on the detailed acoustical fundamentals included in the original while added practical formulas and simulation methods for practicing professionals."--Acoustics Today, October 2012, page 48 Review Magazine.com, January 9, 2013 ".this reference work could be regarded as the counterpart to the advanced, computational acoustic engineering software such as Comsol now becoming popular, providing much of the grounding for these multi discipline, coupled modelling programs.It is a welcome surprise to see Leo Beranek's Acoustics so exhaustively revised."--Audio Review Magazine.com, January 9, 2013 "Beranek and Mellow.offer engineering students a textbook on acoustics that can also serve as a reference for experimenters and consultants. They assume knowledge of electric circuit theory."--Reference and Research Book News, December 2012

"It contains more recent and additional material, including material that is difficult to find elsewhere..this highly recommended book is a treasure of information and problem-solving technique for both the novice and expert in the areas of acoustical transducers and fields."--Journal of the Acoustical Society of America, September 2013 "Even to those that already own a copy of the 1954 edition, I would recommend acquiring a copy of the revision.
