摘要

研究了考虑风速和方向的城市控制交叉口上噪声源的传播问题。声场被描述为来自许多点源的波的叠加，在两个一对一垂直的方向上运动。以罗兹圣家庭医院附近的十字路口为例，对声压和声强进行了数值模拟。

Sound car radiation from city crossroad

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.
