Description
Short technical description: Field measurement of the acoustic characteristics of road pavements The purpose of this method is to determine the acoustic quality of a specific road pavement at a well-defined location. The test is performed as specified in standard ISO 11819-1. Use is made of a microphone connected to a sound level meter and a radar tachometer, installed on the roadside to measure the maximum sound pressure level and the speed of a large number of randomly sampled passing vehicles. The results are statistically processed into an SPB index (SPBI), which is a good measure of the acoustic quality of the pavement at the measuring site - more particularly, of the influence of the pavement on traffic noise load for local residents.
