Office building, church or concert hall – different usage scenarios have different requirements to the acoustics of a building. With Fraunhofer IDMT's products and services acoustic characteristics of a room can be measured in 3D, e.g. using the Fraunhofer Sphere Array. For simulation and optimization of speech recognition and quality, the SIP toolbox can be used. Further more, our new flat loudspeakers offer ideal solutions for all locations where not only sound, but also an unobtrusive integration is required.
