That's simply another question...

Sound propagates as a movement in a medium. So sound does move mass, but a pulse of sound at some frequency results in the mass ending up in basically the same position in which it started, after the sound pulse has passed.

To end up with a net movement of mass, you need a "DC" sound, such as an earthquake slip, or an explosion, both of which result in a net displacement of mass close to the epicenter.

does making your eardrum vibrate count as moving mass?
