Abstract
All previous studies have been allowed to obtain constructive results when considering a certain type of sound wave (plane, spherical, or cylindrical). In reality, arbitrary sound waves do not possess the properties of the above types, and their consideration is more difficult. At the same time, there are situations when in the local area of space the sound wave is similar to a plane wave, and in each area, the length of which is comparable with the wavelength, the wave can be roughly considered plane.
