Transport Research Centre (CDV) owns a uniquely-constructed trailer in the Czech Republic which serves for road surface noise level measurement using the CPX dynamic method. It is specialised equipment which is in accordance with the ISO 11819-2 standard design used in the Czech Republic. Within the EU, the measurements using the CPX method are conducted by several, primarily research-focused, institutions. In order to determine whether CDV results are eligible for international comparisons, comparison noise level measurement using the CPX method was conducted in the Czech Republic during joint work on the CESTI project (TE01020168 - Centre for Effective and Sustainable Transport Infrastructure) between CDV and Eurovia Services s.r.o. The measurement was conducted by CDV using a specially-constructed trailer. Eurovia used a specially-modified regular road vehicle manufactured in France. Results of comparison measurements at 50 km/h show that the noise level was systematically higher on most surfaces analysed by the Eurovia company. The average difference in 14 measurements was 0.6 dB(A): as far as the measurement uncertainty is concerned, the acquired results are compatible.
