Acoustic roller dynamometer

Driving comfort requirements have long since ceased to be a topic that is only dealt with in the premium class. In addition to consumption and safety assist systems, noise levels inside the vehicle are also an important purchase criterion for buyers of compact and mid-range cars these days. Which is one more reason why many vehicle manufacturers are relying on acoustic roller test systems from RENK when it comes to optimizing their vehicles.
