Acoustic Consulting
A pleasant and effortless communication of speech and music requires room acoustic conditions that are optimally designed for this purpose. We advise you on the acoustic planning of complex rooms, from music rehearsal rooms and lecture halls to theatres and concert halls. We offer measurements according to ISO 3382, assessments acoording to DIN 18041, and expert opinions considering the architecture and the history of the buildings and the related practice of music and speech. With state-of-the-art methods of room acoustic simulation at the Audio Communication Group of TU Berlin, we can make the results of room acoustic planning audible even before implementation.

With modern loudspeaker systems and digital signal processing, precise solutions for complex sound reinforcement tasks can be achieved. We are able to find optimal solutions for any kind of environment, including open air concert venues, churches, train stations, sports stadiums, lecture halls etc. We offer a detailed planning and prognosis of sound reinforcement systems, using tools such as EASE 4.4 and EASE SpeakerLab for simulation and TU Berlins auralization laboratory to make the results audible through a simulation already in the planning stage.
