Leisure and sports facilities (figures 5/1 and 5/2 ) often involve high noise emissions. Typical examples of leisure facilities are fairgrounds, open-air theatres and pleasure grounds. Examples of sports facilities are soccer grounds, public soccer grounds, tennis courts, outdoor pools, shooting ranges and sports stadiums.

Motor sports facilities and model flying fields are also sports and leisure facilities. In contrast to roads, which are line sound sources, these facilities are mostly area sound sources and consequently produce more noise.

Noise emissions are produced by technical equipment and machines (e.g. loudspeaker and motorbikes), by users and spectators (e.g. cheering) and by car parks belonging to the facility.

Noises from sports and leisure facilities are often the reason for conflicts between neighbours. The need for rest from one part of the population is opposed to the desire to use adjacent leisure facilities from other parts of the population.

Characteristic features of noises from sports facilities are for example frequent level variations (impulsive noises) and the use of loudspeakers. This is what distinguishes them from for example industrial noises. Noises from sports and leisure facilities must therefore be assessed separately and not through the schematic formation of average levels.
