Summary on Grant Application Form |
|
Much of the previous publications have concentrated on the sound field due to a stationary monopole source above an absorbing ground. However, transportation noise sources are neither stationary nor monopole in nature. The current available theory is unlikely to be adequate for a source travelling at a non-negligible Mach number such as a motor vehicle travelling at high speed, a high speed train, and advancing helicopter or aircraft approaching an airport during landing (or taking-off). Here, in this context, we see that there is an urgent need to redress the balance and to investigate the sound field for a moving directional source above an absorbing surface in a complex outdoor environment. In addition, there is also a need to develop an efficient numerical scheme to compute the sound field in more realistic sound speed profiles over a mixed impedance ground and over a barrier.
