Noise Patrol

Noise Patrol is a unique system for the measurements of vehicle noise and the objective evaluation of the noise in accordance to the prescribed standard. Vehicles have a prescribed sound level at specific revolutions, so an appropriate measurement method is required. Using a smart device, the system significantly facilitates and increases the reliability of field measurements.


Noise Patrol is an all-in-one and easy-to-use system designed for automatic measurement of exterior exhaust noise from road vehicles under stationary conditions, with simultaneous fully integrated RPM detection. (In accordance with 70/157/EEC and ISO 5130.) The system documents results and enables printout of reports on the spot.

Noise Patrol is intended for:

  • The measurement of exterior exhaust noise levels from motorbikes, cars, trucks and mopeds under stationary conditions with integrated RPM measurement control.
  • Vehicle noise inspectors, police officers and race track noise inspectors performing noise checks.
  • Vehicle manufacturers performing final checks prior to customer delivery.
  • Non-contact measurements of engine RPM by computing the engine speed from the acoustic signal of the exhaust noise.
  • Measurements of engine RPM through an OBD 2 interface, external Tacho interface (AVL) and inductive clamp interface.
  • The automation of the measurement work flow, in accordance with ISO 5130.
