An Initial Ambient Noise Model Evaluation Methodology,

Abstract

This report addresses several considerations which will impact ambient noise evaluation, and provides an Initial Model Evaluation (IME) methodology for omni and horizontally directional ambient noise models. Inasmuch as ambient noise model evaluation for vertically directional models or temporal noise models involves both the criteria given in the IME and a number of other considerations unique to the models assumptions, it was considered better to address just the most widely used types (i.e. omni and horizontal directionality noise models) in this effort. Furthermore, consideration is restricted to the two major mechanisms of low-frequency noise: shipping and wind. Noise due to seismic, biologic and other meteorological phenomena is assumed to be minor or negligible at the frequencies under consideration.
