The results or an experimental study ot the evolution ot the shape ot nonlinear second-sound pulses in superfluid He-II are reported The pulses propagate in the bulk (3D geometry) and along a cryoacoustic waveguide tilled with liquid helium (quasi-ID geometry) at temperatures corresponding to the...
