Method of Integral Equations in Problem of Sound Diffraction on Bodies of Non – analytical Form

The real scatterers have non – analytical form and therefore the method of the division of the variables does not approach by the calculation of the reflection from their. In the article is presented the method of the integral equations Fredholm of the first and second kinds for the solution of the problem of the sound diffraction on the ideal non – analytical scatterers. In detail is giving the analysis of the improper integrals and are calculating the moduluses of the moduluses of the scattered pressure for the non – analytical bodies.
