principle

Two high sensitive microphones record the noise level of the measuring tyres (one emulates passenger cars, the other emulates heavy cars). To eliminate interference noises, the measuring area has to be highly sound absorbing and kept far from the motor noise of the vehicle, so the trailer conception was chosen.

CPX noise measurements are performed in compliance to EN ISO/CD 11819, part 2.
