An analytical solution is proposed for a plane problem on the action of non-stationary pressure on a layer of compressible fluid. The corresponding linear problem of hydroacoustics is stated. The integral Laplace and Fourier transforms are applied. In the case of a fixed loading domain, the transforms are inverted using tabulated formulas and convolution theorems. As a result, the expressions for speed and pressure at an arbitrary point of the fluid are derived in closed form. The solution is represented as a sum in which the mth term is the mth reflected wave. Retaining a certain finite number of terms in the solution gives the exact solution of the problem on a given time interval taking into account the necessary number of reflected waves. The variation in pressure with time and space coordinates is calculated.
