Application of sound propagation (in the Persian Gulf and Oman Sea)

Abstract

As it is a real concept in nature, more than 70% of the earth surface is covered by water such as Seas and oceans. Surface water on the earth is linked together. Knowing phenomena and organisms underwater has been a purpose in human life; why this aim is used in some industries and sciences. Sound is known as a mechanical wave with many applications in seawater. Obstacle, organisms, objects and even each purpose like a driver, a mass of particular fish or sediment types on the bottom could be recognized and be studied when their physics and properties would be known. Acoustics as an applied science as a regards of much research importance using mechanical waves moving underwater is a helpful tool to reach this useful scientific aim. In this paper following a one year study and research after explaining application of some marine acoustical instruments, horizontal and vertical sound propagation created by some particular instruments will be analyzed.
