Ocean acoustics is the screening of sound changes and their character in the ocean. Sound-pressure waves are formed by vibrating underwater objects, which in turn compress water molecules. And sound waves travel through the ocean. Sound waves emanate in all directions away from the source, like a wave on the surface of the pond. Compressions and decompression associated with sound waves are found in our ears by pressure changes by structures and most man-made sound receptors such as a hydrophone, or underwater microphone. Let's know more about Ocean Acoustic.
