Persistent noise leads to adverse effects which can be avoided through active noise protection. That's why lasting protection from persistent noise pollution is the object of our environmentally sound, noise-reducing concepts, designs and verifications. The relevant regulations form the basis of our acoustic tests in all categories: road, rail and air traffic and urban development.
