Acoustic environmental impact of stadiums

摘要

Stadiums are usually built close to cities, or even sometimes into urban areas, mainly to make the access to the sport facilities easier. In this paper a methodology to predict the acoustic environmental impact of such buildings in the neighbourhood is presented. Firstly, a ray tracing simulation tool for complex spaces (ICARE) is used to characterize the stadium as an equivalent sound source, taking into account the geometry of the stadium, its material properties, and the sound sources present into the stadium. Then the equivalent sound source is implemented into the MITHRA ray-tracing code which takes into account topography, buildings, roads or meteorological conditions. At last the acoustic environmental impact of stadium can be evaluated. In this work the stadium can be used for football matches as well as for concerts.
