Since propagation distances are large, the computational cost of such techniques often exceeds the available computer resources. In this study, a number of deterministic prediction techniques are evaluated for the analysis of traffic-induced noise propagation in such complex environments. The goal is to identify the particular strengths and weaknesses of the various methods, encouraging cross-fertilisation and ultimately yielding the development of hybrid solution schemes which combine the strengths of the different methods. A specific point of attention is the treatment of non-reflective boundaries in simulating an unbounded atmosphere, which is often a big challenge in full-wave prediction techniques. The numerical simulations in this paper are limited to a homogeneous and still atmosphere.
