A newly constructed road in the province of North Holland in the Netherlands (N201) had to meet all the requirements of the Dutch Noise Scheme and the Dutch Nuisance Act. In order to fulfil the accompanying strict noise limits, a noise reducing pavement has been applied. However, after reconstructing, numerous complaints occurred about annoying noises caused by passing trucks. An investigation has been executed to determine objectively the possible source of these complaints. Emission measurements have been performed as well as psychophysical analyses based on immision measurements to identify possible tonality and saliency of the noise immisions. Simultaneously, a questionnaire had to be filled in by the inhabitants of the adjacent residential areas. Since it became clear that almost 100% of the measured heavy vehicles emitted a tonal noise, additional FFT measurements of passing-by trucks have been performed to identify the sources. With all the results, some appropriate measures against the occurring tonal noise have been advised.
