More than 25 per cent of the population in Europe are exposed to noise levels exceeding guidelines for road traffic noise
Road traffic is a major contributor to environmental noise, particular in urban areas. More than 25 per cent of the population in Europe are exposed to noise levels exceeding guidelines for road traffic noise. Therefore the EU and national governments have had noise on the agenda for many years. COWI has been involved since 1979 when the first noise mitigation projects were introduced.
We are an experienced partner in connection with:
We use the noise calculation programme SoundPLAN and CadnaA to calculate road traffic noise. Results are presented in an easily accessible form using coloured noise contour maps. We offer easy-to-understand presentations including colour maps and sound demos based on many years of experience with public hearings and enquiries.
Noise and vibration are significant environmental issues along railway lines. A number of initiatives are under way to improve the situation, e.g. retrofitting of cast iron brake blocks, improved track design and construction and TSI regulations of rolling stock.
We offer the following services:
COWI uses the latest technology and software. In noise and vibration mapping projects we use GIS and available databases in order to make the mapping as fast and efficient as possible. Noise issues are presented in an easily accessible form.
Surveys have proven that noise from aircrafts is the most annoying source of transport noise, meaning the noise at a certain level is most annoying when it is caused by aircraft movements.
Noise from airports is regulated by standards from the International Civil Aviation Organisation (ICAO) and the EU. COWI calculates noise levels from take-off and landing as well as from noisy ground operations like engine testing, workshops and ground power units (GPU).
