Abstract :
The sound generation from vehicles moving on the right-angle bend on city road with taking into account of wind effect in the acoustic field is considered. A solution of the problem is found using the integral Fourier transforms, stationary phase method and superposition of many partial solutions. The numerical analysis of traffic noise characteristics is carried out for the case of dual-carriageway Zjednoczenia street in the town of Zielona Góra, Poland.
