Industrial and recreational noise could be generated by a multitude of different sources and processes. Industrial noise can be generated by factories and plants (i.e., product fabrication or assembly), power generation (hydroelectricity or wind turbines), construction activities, or agricultural and meat processing facilities. Sources of recreational noise vary widely but they can include music festivals[5], shooting ranges, sporting events, car racing, woodworking, pubs,[6] people's activities on the street,[7] etc.
