A study has been made of the drift velocity of particles in an acoustic resonator at the first resonant frequency in standing and periodic shock waves. The notion of a local equilibrium velocity of particle drift has been introduced. A family of problems on the particle drift has been investigated numerically at different Mach and Reynolds numbers. The drift velocities of a particle have been plotted versus the drag coefficient and the position. The drag coefficient at which the particle drift velocity peaks has been found. At small and large drag coefficients, the particle drift velocity tends to zero. It has been shown that the maximum velocity of particle drift in the standing wave is one to two orders of magnitude smaller than that in the periodic shock wave.
