• To predict noise within 100 meters from a bridge and within a few meters above the ground, measurements of the sound exposure level, L_<AE>, at four positions are required. The process of noise generation is modeled by a homogeneous line of point sources with dipole directivity. Noise propagation is governed by geometrical spreading and ground effect, which is modified by the other wave phenomena, particularly atmospheric turbulence. To illustrate this method, measurements and calculation were performed at the Nishitetsu Line Bridge over the Nakagawa River in Fukuoka.
