Abstract
In the previous paper, the authors proposed the forms and dimensions of noise barrier which is able to reduce not only road traffic noise but also wind load through scale model experiments in an anechoic room and two-dimensional wind tunnel. Furthermore, in this paper, a field test was done using a vehicle running at a constant speed in order to prove enough noise reduction before practical application. The barrier was 90cm high. The louver made of steel was covered with absorptive material of 3cm thickness and the intervals of its members were 45 or 50cm.
