騒音・風速2点同時実測による盛土道路周辺の風況及びその音響伝搬への影響調査 [in Japanese] INVESTIGATIONS OF WIND CONDITIONS AROUND A ROAD EMBANKMENT AND THEIR INFLUENCE ON SOUND PROPAGATION BY TWO-POINT SIMULTANEOUS MEASUREMENTS OF NOISE AND WIND VELOCITY [in Japanese]

It has been known that the road traffic noise propagation is affected by the wind. However, not so many studies deal with the effect in conjunction with microscopic wind conditions. In the present study, wind conditions around a road embankment and their influence on sound propagation were investigated by two-point simultaneous measurements of noise and wind velocity in an open suburban area. Results show that (1) the wake turbulence by the embankment affects variance in received sound pressure levels, (2) the wind velocity component parallel to the road could also be affecting sound propagation.
