Noise reduction at the source are in most cases the technically and economically best solution to noise nuisance. An example is road traffic noise. Usually, measures such as noise screens and facade changes are implementet to reduce traffic noise. These are relatively expensive measures, which also have proven to have limited effect on traffic noise nuisance. SINTEF ICT are working on methods and technicques to characterize noise sources, both theoretically and through measurements.
In particular, work is going on to analyse road surfaces with regard to noise, and to measure tyres to examine the noise reduction potential at the source.
SINTEF ICT also participates in various international committees (e.g. ISO, ECE/GRB) which are working on improved measurement methods, and limits on noise emission from tyres and vehicles, which is intended to reduce the noise at the source.
