In this paper, the underwater acoustic decay performance of polymer solution is studied. It is found that the decay effect of water acoustic in solution increases regularly with the increase of solution concentration. The characteristic of solution can be described by Maxwell model in underwater acoustic propagation. The factor α has a linear relationship with the solution concentration c, and the slope of the line is greater than zero and related to the frequency of underwater sound
