Independent macroscopic motions and several sounds in a superfluid liquid implies unusual effects in the Doppler shift which becomes a nonkinematic phenomenon. As it was recently shown [2] the Doppler shift of fourth and first sounds is characterized by a nontrivial temperature dependence. Moreover
