Flex Acoustics has developed and patented the groundbreaking Evoke™ technology, a new product for variable acoustics. The evoke is a powerful variable acoustics technology which transforms a hall acoustically in five seconds – with barely any visual change to the room or hall. Flex acoustics is also responsible for scientific research concerning recommendable room design for pop, rock and jazz performances: Suitable reverberation times in halls for rock and pop music, JASA 2010 and others. Our founder and Director Adelman-Larsen also authored the first scientific book on the subject of acoustics for amplified music on Springer Verlag. Now on second edition, order “Rock and Pop Venues: Acoustic and Architectural Design” on Amazon or direct from Springer!
