ABSTRACT
In Directive 2002/49/EC of the European Parliament and of the Council of 25 June 2002 it states (Annex IV) that strategic noise maps for agglomerations shall put a special emphasis on the noise emitted by (see Figure 6.1)1:
• Road trafc • Rail trafc • Airports • Industrial activity sites, including ports

Industrial noise sources are different from transport noise sources because of its constant presence at the same position. Transportation noise sources are based on a large number of cars, trains, or airplanes, divided into subcategories, and depending on speed, pavement, and so forth. But industrial noise may be just one fan operating for over 20 years. Industrial sources range from this fan (sizes less than one metre to several metres in diameter) to all kinds of equipment (for instance trucks, lifting trucks, and crushers), and complete reneries and power plants.
