Noise monitor 2016 : Validation of motorway and railway noise

Geluidmonitor 2016 : Meting en validatie van geluidproductie door rijkswegen en spoorwegen


Noise levels measured at 38 sites along motorways in 2015, on average were 2 decibel higher than calculated values. At 39 measurement sites along the track, the measured and calculated noise levels in 2015, on average were in agreement. These results are consistent with previous years, 2013 and 2014.

At the individual measurement sites, both for motorways and the track, differences may vary from the average. At motorways the measurements are within 2 dB lower and 6 dB higher compared with calculated values, depending on the type and the local condition of the road surface.

The comparison of measured and calculated noise levels is a requirement of the environmental management Act. The road- and railway infrastructure manager, Rijkswaterstaat and ProRail, show by calculation whether the noise production from the road or the track complies with established noise limits. The calculated noise levels are validated by RIVM with a sample of measurements.

This report also gives the latest results of measurements from 2016 at 45 sites along motorways and 40 sites along the track. The measured noise levels from 2016 will be compared with calculated levels, which will be published by the road- and railway infrastructure manager in the second half of 2017.
