Abstract:

A computer model for calculating the vertical and horizontal directionality of ambient noise and some of the results which have been obtained are discussed. The model considers three sources of surface-generated anisotropic noise, one source of surface-generated isotropic noise and two sources of volumetric isotropic noise. Noise levels are obtained for various propagation conditions and for different sensor depths. Results agree well with experimental data, and it is shown that the model can be a useful tool in the planning of ambient noise measurement experiments and in the analysis of results.
