Noise performance evaluation: comparison of laboratory and in-situ methods

The main objectives of  WP 4 are:

to collect and examine tests and results from laboratory and in-situ measurements, according to EN 1793-1 and -2, CEN/TS 1793-5 and to the new method developed in WP3;
to analyse the relationship and acoustical correlation between those different tests;
to create a database of all acoustic and non-acoustic properties of different types of European NRD;
to provide data for future analysis and prediction of long-term performances;
to help manufacturers and road administrations to choose suitable methods to assess the NRD performance and to correctly estimate the lifetime acoustic behaviour of novel products for CE marking.
