An analytical formulation for the calculation of the range and depth-dependence of
propagation loss in isospeed water is introduced. The range-dependent bathymetry is …

Underwater sound is a critical tool for aquatic animals that communicate acoustically or
exploit environmental sounds to find prey, avoid predators, or for orientation [Slabbekoorn et …

Abstract The European Union requires member states to achieve or maintain good
environmental status for their marine territorial waters and explicitly mentions potentially …

The field of underwater acoustics has been extensively developed over the past four
decades in response to practical needs originating within both the naval sonar and the …

Passive sonars attempt to detect sound radiated by vessels of interest. This detection takes
place against a background of noise, with important sources of noise including distant …

Passive-sonar-performance modelling requires the accurate estimation of the acoustic field
for a broad range of frequencies in various environments. In this paper, we assess the …

Foi realizada uma análise de modelos numéricos de propagação do som em ambiente
marinho e selecionados dois modelos para serem aplicados em três cenários …
