Noise Patrol
The definitive measurement solution for stationary exhaust noise testing

Noise Patrol provides an all-in-one, easy-to-use system designed for automatic measurement of exterior exhaust noise from road vehicles under stationary conditions, including simultaneous, fully integrated RPM detection. The system supports various other RPM detection solutions as required by local legislation or preference (AVL, OBDII direct interface, …).

Measurements are performed completely according to ISO 5130 standard and SLM is IEC61672 Class 1 compliant. Adaptation to local legislations or directives is possible and can also be locked so that only a master user can perform these changes.

Capabilities:
- Exterior exhaust noise level measurement of motorcycles, cars, trucks and mopeds under stationary conditions (engine sweep test) with integrated RPM measurement control
Uses:
- Real‐world, on‐site testing: Vehicle noise inspectors and police officers
- Exhaust R&D and production testing: Integrating in the development or production test process for motor vehicle exhaust systems
- Car, motorcycle or truck production line testing: Performing final checks prior to customer delivery
