A Bayesian network is developed to demonstrate the feasibility of using environmental acoustic feature vectors (EAFVs) to predict underwater acoustic transmission loss (TL) versus range at two locations for a single acoustic source depth and frequenc

Acoustic transmission loss (TL) has been computed using oceanography modeled by the Navy Coastal Ocean Model (NCOM) over an 18 month time period in the Western Pacific Ocean [Jacobs, G. A., J. G. Richman, J. D. Doyle, P. L. Spence, B. P. Bartels, C.

Ocean analyses, forecasts and ensembles characterizing oceanographic uncertainty are becoming widely available. Acousticians are interested in the impacts of oceanographic variability (temporal and spatial) and uncertainty on acoustic propagation, ho

Broadband noise due to surf that propagates kilometers out to sea with little transmission loss has been observed for many years, but rarely directly measured and characterized. In October of 1994 a coastal research experiment, DUCK94, was conducted

A Technical Metrics Workshop was held at NRL Stennis Space Center, MS, by the NRL Acoustics Division April 29 — May 1, 2008. The primary goal of the workshop was to identify the state-of-the-art technical and scientific metrics for the acoustic and

Proper characterization of underwater acoustic transmission loss (TL) relies on proper treatment of the air/water and water/sediment interfaces. This paper will focus on how the air/water interface is treated in parabolic equation (PE) models such as

A metric is presented for quantifying the difference between two acoustic transmission loss curves. This allows a fast, but more importantly, consistent way to determine how well two underwater acoustic transmission loss curves compare in terms of th

As computer capabilities continue to increase, characterization of the oceanic environment improves both spatially and temporally. This oceanographic information (specifically sound velocity) is often used to make acoustic predictions, but wide-area

Signal excess (SE) is often used as a metric for determining acoustic performance through a waveguide or over an area. This quantity can limit the capability to assess the environment because SE is computed given a single acoustic source, receiver an

Ambient noise due to surf has recently been empirically characterized as a source level density (SLD) per meter of beach as a function of wave height and frequency [Wilson et al., IEEE J. Ocean Eng. 22, 425–433 (1997) and J. P. Fabre and J. H. Wils
