Operational Acoustic Transmission Loss Uncertainty Characterization

Abstract

Uncertainty is an unavoidable part of any physical measurement or prediction process. Uncertainties in directly measured oceanographic quantities such as bathymetry, water sound speed profiles, acoustic system parameters, and so forth are fairly straightforward to quantify. A method for mapping these values into overall uncertainty in sound transmission loss (TL) levels has been developed at NRL. Here, we briefly review this method and demonstrate its use in a larger framework, incorporating environmental and acoustic prediction models and associated uncertainties to give a unified, operationally useful prediction for confidence intervals on acoustic transmission loss.
