Tyre/road noise
Our services include measurements to determine the acoustic quality of road surfaces, for example using the CPX trailer measurement method, as well as specific measurement methods and analyses for acoustic optimisation of road surfaces.
Building physics
Our expertise includes building and room acoustics as well as thermal building physics, building ecology and energy efficiency consultancy.
Software
We specialise in developing environmental databases, noise calculation software, information systems and documentation – all tailored to the needs of our clients.
Research & development
We can count on an extensive national and international network in practice-oriented research in our key areas.
Environmental noise
We specialise in acoustic measurements and finding solutions to reduce noise emissions and vibrations from road traffic, railways, shooting ranges, commercial and industrial properties, building sites, etc.
