Race Technology Vorbeifahrgeräusch-Messsystem

We offer complete pass-by (drive-by) noise testing systems suitable for both cars and motorcycles. The systems are based around a compact, customised Peli case that mounts on/in the vehicle and a trackside PC and sound meters. With a wireless data link between the vehicle mounted kit and the trackside PC. All data and results are recorded to the trackside PC in the Performance Monitor software, and test results and data are feedback to the vehicle mounted display for instant feedback.

The system is ideal for the motorbike testing as the vehicle mounted kit is compact and easily mounted. The trackside set up is quick with only a single measured distance between the optical trigger and the sound-meters. Passing the optical trigger starts the test at point A-A, with the system automatically measuring the distance to P-P and B-B, with relevant speed and sound measurements recorded to the PC. The testing can be made more efficient by using a second optical trigger, allowing testing in both directions, with automatic left/right switching of the sound-meters.

For the motorcycle test system the laser trigger and GPS antenna are mounted neatly on the case, for a car or lorry these would be mounted on the outside of the vehicle.

The image above demonstrates the compactness of the system, showing it mounted on a motorbike, complete with display for live feedback. The system is CAN compatible and can take RPM and throttle position directly from the vehicle's CAN bus. If CAN is not available on the vehicle then a separate direct RPM input is available and a 100% throttle switch can be quickly mounted as shown below:
