man-made noise levels are based on measurements
performed in the 1970s. Some measurements have been
carried out since then, showing that noise caused by
automotive ignition systems has been reduced, but manmade
noise in business areas and city centers increased,
especially due to the widespread use of electronic systems.
The interference scenario also changed, from analog
communication systems in relatively free-space conditions,
to digital systems in living areas, often semi-enclosed such
as offi ces, industrial production plants, and even inside
cars and trains. Several measurements have therefore been
carried out to estimate the level of man-made noise in these
