Noise testing
Do you hear it?
The growth in traffic and the increase of motorised machinery and equipment lead to increased noise. Research and development in the area of mobile and immobile sources of noise is therefore gaining in importance. We have spent more than 20 years on applied research and development tasks for motor vehicles and other mobile sources of noise.
What is important in causal research are the detection, localisation, and analysis of noise sources as well as measures for its reduction. The field is broad: It ranges from the measurement of individual noise sources to investigations into the development of measurement and test cycles all the way to basic research in the context of national and international research projects. An important field of work is tyre-pavement noise. An ISO test track is available. Comprehensive advice on acoustic and accompanying measurements with the aim of creating measures to reduce the noise produced by engines, machines, or vehicle components is also among our services
