BASICS OF REGULATIONS
Regulations are meant to set a policy and specify limits. As opposed to standards, their application is compulsory. As an example, they may provide noise level limits for community noise control, transportation noise, or occupational noise control purposes. They may also provide minimal acoustic requirements for various types of buildings, such as dwellings and schools.
Due to the technicalities involved in Europe, the trend is more and more to rely on standards that are quoted and referred to in the legal texts.
One might care to remember that regulations are not meant for comfort! They simply provide the bare minimum acoustic requirements.
Regarding transportation noise, limits are stated using noise levels over specific spans of time (e.g., daytime or nighttime period). Equipment noise may be covered using noise level limits (e.g., ) or the emergence (gap between the ambient noise measured with the equipment in operation, and the background noise level without the equipment operating) (e.g., ).
