M+P

We have developed our own measuring system, which we can use to conduct measurements in all kinds of circumstances. A great advantage of the M+P trailer is that the effect of any source of interference is minimal. The M+P trailers are fitted with a sound-absorbing casing (a semi-anechoic chamber). This keeps the microphones shielded from wind noise and interference noise from the background traffic and the towing vehicle. As a result, no further traffic measures are necessary when performing CPX measurements and the M+P trailer can be deployed in any situation... The CPX trailer is a practical instrument for the rapid measurement and assessment of the sound properties of longer sections of road surfaces. Anyone involved in laying a low-noise road surface will certainly be familiar with the corresponding noise-reducing requirements. The CPX method is the most widely-used approach for determining whether the low-noise road surface meets these noise-reducing requirements.
