The High-Power Acoustical Warning System

Most high-power warning systems work in open space, particularly in urban areas, and are also used for spoken messages, not only for alarming. The useful coverage depends upon used transducers and installed electrical power. Most of these systems have omnidirectional coverage. The environmental conditions and miscellaneous barriers have an influence on the sound propagation for warning and informing systems. The computer simulation was done which takes all these parameters into account, and enables calculation of needed acoustical and electrical parameters.
