High quality acoustics that enhance performances and support localization of audio sources are a key factor for classical concerts, operas or theatre performances. Sound reinforcement systems designed for such events should not only aim to achieve an excellent sound amplification, but also to recreate the most similar spatial and acoustical impression. Under this premise, Fraunhofer IDMT has developed its “SpatialSound Wave” 3D audio system based on our ten-years experience collaborating with different opera festivals and the long time development of Wave Field Synthesis.

Niels Werner Adelman-Larsen of Flex Acoustics will demonstrate during "Low-Frequency Control Workshop" in the MMR (Workshop 5, Day 2), the effectiveness of acoustic absorption at low frequencies using a number of 7 meters long inflatable tubes installed along the walls "but also where wall and ceiling meet since there we get an enormous LF pressure build up" says Niels. 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 which 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. An accompanying paper presentation will cover the details of "New Technologies for Passive Low-Frequency Absorption and Case Studies in Sound Reinforcement Applications". The tubes were recently employed to control the acoustics for 8 Kraftwerk concerts in the Berlin “Neue National Galleria” and at the Eurovision Song Contest in Copenhagen.
