Abstract :
The noise propagation from moving sources on city controlled intersection with taking into account the wind velocity and direction of is investigated. The acoustic field is described as the waves superposition from many point sources, moving in two one-to-one perpendicular directions. Numerical results are obtained for acoustic pressure and sound intensity generated, in particular, on crossroad near St. Family Hospital in Lodz.
