The paper considers the use of two options of conjugation of wave fields in the method of partial domains: the first is the conjugation of wave fields in the sense of the root mean square approximation, the second is the pointwise conjugation of wave fields. A solution is obtained for the problem of radiation from one or two flat pistons into a wedge-shaped waveguide. It is shown that with the same number of modes in partial domains, the version of the root mean square approximation is more accurate. A quite acceptable calculation accuracy was obtained for the option of pointwise conjugation of fields at a certain value of the wave distance between the nodal points.
