The full program of tutorials, workshops, demonstrations and paper presentations has been announced for the AES 59th International Conference, with an emphasis on Sound Reinforcement Engineering and Technology, taking place July 15-17, 2015, at McGill University in Montreal, Canada. The program is constantly being updated with new workshops and events.

A recent addition to an already exciting program, “Low-Frequency Control Workshop”, will be held on July 16, 12:00 p.m. - 1:15 p.m. in the Schulich School of Music’s Music Multimedia Room (MMR), and co-hosted by Flex Acoustics. Using Flex Acoustics Inflatable Membrane Low-Frequency Absorbers, Niels Werner Adelman-Larsen of Flex Acoustics will demonstrate the effectiveness of passive acoustic absorption at low frequencies using a number of seven-meter-long inflatable tubes, some installed along the walls, but some “…installed where wall and ceiling meet since we get an enormous LF pressure build up there,” says Niels.

on Sound Reinforcement.

Research shows that too much low-frequency reverberation is the primary source of an unpleasant sonic experience perceived by musicians as well as audiences during amplified music concerts. Flex Acoustics offers a new, patented technology of inflated, ultra thin plastic membranes that seem to solve this challenge of low-frequency control and are suitable for multipurpose halls that need to adjust their acoustics at the push of a button. 

The tubes were recently employed to control the acoustics for eight Kraftwerk concerts in the Berlin Neue National Galleria and at the 2014 Eurovision Song Contest held in B&W Hallerne, a former industrial complex located on the island of Refshaleøen in Copenhagen, Denmark.

An accompanying paper presentation will cover the details of “New Technologies for Passive Low-Frequency Absorption and Case Studies in Sound Reinforcement Applications.”
