Underwater acoustic communication is a technique of sending and receiving messages below water there are several ways of employing such communication but the most common is by using hydrophones underwater communication is difficult due to factors such as multi-path propagation , time variations of the channel, small available bandwidth and. Ocean acoustics is the study of sound and its behavior in the sea when underwater objects vibrate, they create sound-pressure waves that alternately compress and decompress the water molecules as the sound wave travels through the sea sound waves radiate in all directions away from the source like.
