Abstract :
The sound radiation from vehicles moved on city road under and above a viaduct is considered. The solution of problem is obtained as superposition of solutions for cases of separate point sources moved on the different heights and in mutually perpendicular directions with taking into account of wind effect. It is the first stage of solution of general problem without consideration diffraction effects from viaduct plate. The numerical analysis of traffic noise characteristics is carried out for one of viaduct in the town of Kielce (Poland).
