Our research and development business has succeeded in several unique acoustic projects in recent years, and several projects are currently being implemented. These are based on experience gained from acoustic planning and consulting assignments and perceived market needs. We produce custom designed software, proprietary interfaces, scaling and optimization algorithms, measurement methods, as well as numerous studies and scientific publications of these. A priority area is the various acoustic applications of artificial intelligence, of which our room shape optimization software has already been proven in several projects. In our work, we are committed to maintaining scientific activity and approach.
