The propagation of steady pressure disturbances through a liquid containing small gas bubbles is investigated numerically. The equations of continuity and motion, together with the complete bubble dynamics equation, are employed. The analysis takes into consideration the effects of relative translational motions between the bubbles and the liquid. The results show the possibility of oscillatory shock waves that start with a steep rise in pressure followed by a relaxation region wherein the pressure exhibits damped oscillations about a final equilibrium value. For strong shocks, the predicted frequencies of pressure oscillations are so high that they may be unsusceptible to measurement. For weak shocks (p2/p1<2), the predicted wave forms are in agreement with the results of previous theories.
