Abstract: Nonlinear equations for zero sound interacting with the B-phase collective modes are derived by treating 3He-B as a medium of two-level ``molecules'' (Cooper Pairs). the nonlinear equations reduce to known results from kinetic theory in the linear response limit. Soliton solutions to the nonlinear equations are discussed in context with recent experiments of Polturak, et al.
