Ever since the end of the 1970s the World Health Organisation has described noise as a major environmental risk. It is a physical phenomenon that affects health, social relations and the economy. The social cost of noise has been estimated at several billion euros in Europe alone.
Acoustic problems arising from noise pollutions are often induced by irresponsible behaviour, but they can also result from poor design in infrastructure and buildings.
Public authorities have therefore set up a list of requirements prescribing minimum acoustic characteristics. More and more project owners and designers are turning to acoustics professionals to meet these requirements.
