The propagation of acoustic waves in a prestrained compressible elastic layer that interacts with a layer of ideal compressible fluid is studied using the three-dimensional linearized equations of elasticity and the assumption of finite strains. The dispersion curves are plotted for modes over a wide frequency range. The effect of prestresses, the thickness of the elastic layer, and the thickness of the fluid layer on the frequency spectrum of normal waves in this hydroelastic system is analyzed. The numerical results are presented in the form of graphs and analyzed
