A noise directionality model including variable bathymetry
In this paper we investigate the noise directionality due to distributed surface sources m several envtronments with a uniformly sloping sea bed. Of particular interest are frequency dependence and the question of the relevance of multipaths to very high frequencies. We look at both uniform source distrtbutions and swathes of sources lying parallel to the coastline. Some closed form solutions are presented, backed up by numerical solutions using the CANARY range and azimuth dependent noise model.
