Abstract
For precise noise prediction, it is important that sound propagation characteristics are incorporated in a calculation model accurately. The authors have already reported that the characteristic is closely related to flow resistance and reflected surface of sound in the homogeneous site. Furthermore, in this paper, the following investigations are dealt with:(1) determination of flow resistance andreflected surface of sound from field experiments, which correspond to field covered with rice plants and bare field respectively, (2) spatial transferability of these values, (3) a new method for calculating flow resistance, which corresponds to road site consisting of two ground strips parallel to the roadway, such as asphalt pavement and field covered with rice plants, (4) excess attenuation effects of these ground strips on equivalant sound level.
