摘要

从理论上研究了城市道路周围运输设施的声辐射与风速和风向的关系。给出了一个运动声源的解，即声源辐射和弹性半空间反射的两个波之和。一般问题的解是许多部分解的叠加。脉冲声的计算结果表明，产生的巷道噪声与风的特性有很大的关系。

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.
