Abstract
The Romanian coastal area of the Black Sea has particularities related to the marine environment, namely a low average salinity and seasonal winter/summer temperature variations that influence the attenuation in volume for the propagation of acoustic signals. In this paper, the influence of the marine environment on the volume attenuation of the acoustic signals was analyzed using different calculation formulas for the attenuation coefficient. For this purpose, the Hydro-acoustic Forcast Modules application developed within the Research Center for Navy was used to simulate the acoustic energy losses.
