Radiation of roadway noise in windy conditions

The sound radiation from transport facilities moved about city road is investigated theoretically with respect of the velocity and direction of wind. Solution for one moving sound source is presented by a sum of two waves, radiated from source and reflected from an elastic half-space. The solution for general problem is obtained as superposition of the many partial solutions. Calculated results for pulsed sound show that the generated roadway noise is significantly dependent on the wind characteristics.
