Calculation of road traffic noise
Noise pollution is generally determined through calculations. The calculation of road traffic noise is based among others on RLS-90 (Guidelines for noise protection measures at roads). This method of calculation is very complex as sound propagation is influenced by a number of parameters. There is a simplified method of calculation for long and straight lanes, which provides orientation values for a general view.
Our decibel calculator helps you to determine the relation between average sound level and traffic volume, truck percentage, speed, road surface, gradient as well as the distance to the sound source (and the depending degree of absorption). What cannot be considered is topographic characteristics, barriers and development. The decibel calculator gives you values for the individual parameters you have filled in. The starting point is always the average sound level in a distance of 25 m and the speed limit is set at 62 mph (100 km/h).
