From this, locations of high and low signal intensity may be computed, which are useful in the fields of ocean acoustics, underwater acoustic communication, and acoustic thermometry . A ray tracing of acoustic wavefronts propagating through the varying density of the ocean. The path can be seen to oscillate about the SOFAR channel. Optical design

This tutorial example illustrates how to set up several important features using the Ray Acoustics interface. It illustrates the intensity and phase calculation in graded media (speed of sound profile) including frequency-dependent attenuation in seawater (using a semiempirical model from literature). Two different boundary reflection models are used for the sea surface and the …
Underwater acoustics - Wikipedia
https://en.wikipedia.org/wiki/Underwater_acoustics
Underwater acoustics is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries. The water may be in the ocean, a lake, a river or a tank.Typical frequencies associated with underwater acoustics are between 10 Hz and 1 MHz.The propagation of sound in the ocean at …
