A phenomenological theory for the propagation of the real squashing modes in superfluid {sup 3}He-B is presented. This allows one to calculate the splitting of the real squashing (rsq) mode spectrum caused by the combined effects of magnetic field, dispersion, and texture in the experimentally important range of magnetic fields from 0 to 10{sup 3} Gauss. This serves to provide a tool for the rsq-mode spectroscopy of the {cflx n}-textures in {sup 3}He-B. In particular, a new gyrosonic effect is suggested: the intensity of the rsq modes generated in textures depends on the sense of rotation - even when the axis of rotation {cflx {Omega}} coincides with the direction of the ultrasound propagation {cflx q}.
