Detail

Main advantages

We offer accredited measurement of road surface noise using the CPX (Close-ProXimity) method, which allows accurate assessment of the noise produced by the road surface in contact with the tyres. The measurements are carried out in accordance with ISO 11819-2, ISO/TS 11819-3 and ISO/TS 13471-1, which guarantees high quality and comparability of results. We use a specialised CPX trailer of our own design, which enables dynamic noise measurements over a distance of up to 15,000 km per year. The results are corrected for reference speed and temperature, providing comprehensive data for road managers.
