This facility is ideal for measurement and analysis of the interior noise of vehicles, as well as measurement of intake and exhaust system noise. Suitable for vehicles ranging from subcompact passenger cars through to trucks and buses with twin drive axle this dynamometer provides a repeatable environment for detailed measurement and provides an opportunity to complete disconnect work in complete safety.
