Research Abstract |
A numerical simulation method on outdoor sound propagation based on FDTD which can take into account arbitrary meteorological conditions in residential area obtained by CFD has been developed. A new hearing system of numerical simulation results has been proposed by using a 6-ch. sound reproduction system and a dummy head microphone. Sound propagation of railway noise to a receiver at about 70 m in height has been monitored throughout a year and the influence of meteorology on sound propagation from ground to a higher position has been investigated.
