This paper gives the fundamental equation of underwater sound propagation. When the problem such as seaquake is solved in time domain, the interaction between free-surface waves and underwater sound waves should be considered. We have to use the governing equation of the underwater sound propagation on the fields with gravity effect at that time. In this paper, the equation that governs the sound propagation is derived based on the combined theory of sound and gravity waves. Then the final governing equation of sound propagation in the water with gravity effect is expressed by means of the formula of thermodynamics.
