Niels Werner Adelman-Larsen

Managing Director of Flex Acoustics

Niels Werner Adelman-Larsen holds an M.Sc. in acoustic engineering from the Technical University of Denmark, as well as a Ph.D. in acoustics from Aalborg University. Before pursuing his professional career as a musician, he studied music and sound engineering at Berklee College of Music on a scholarship, and took a B.Sc. completed with a thesis on room-acoustics for sound studios.

So far, he has played more than 1,200 jazz, pop and rock concerts around the world. Throughout those concerts, Niels learned that most halls are, in fact, unsuitable for amplified music such as pop and rock. This hands-on experience led him in 2004 to initiate the first profound scientific research projects within acoustics for amplified music venues ever conducted. A field he has since almost solely developed.

Niels'  investigations led to peer-reviewed research articles, as well as the only scientific book about acoustics suitable for amplified music (Springer Verlag) and to the ISO:23591 standard. His research and ideas are widely applied by acousticians around the world on a daily basis.
