Exhaust Noise Inspector

Brüel & Kjær Exhaust Noise Inspector is a complete all-in-one system designed for automatic measurements of exterior exhaust sound level from road vehicles under stationary conditions, simultaneously with RPM detection.

The noise level and engine RPM are measured with the same microphone. A large display showing all the necessary information and an additional RPM Indicator, allow extremely simple and quick measurements, in accordance with the standards.

Local authorities and police inspectors will appreciate the ergonomics of the system, allowing measurement to be performed by one single operator.

• Measurement of exterior exhaust sound level from motorbikes, cars, trucks and mopeds under stationary conditions (engine sweep test)
• Non-contact measurements of engine RPM by computing the engine speed from the acoustic signal of the exhaust noise
• Allows totally non-invasive tests of vehicles – the engine bonnet or compartment cover does not need to be opened

For further information please contact your local Brüel & Kjær sales representative.
