No idea. If it does that could be rather destructive on some
materials.

What is clear is that acoustic radiation pressure plays a role.
And that's a subject that has caused a lot of confusion and false
results throughout the history of acoustics as a science. Some big
names (including Rayleigh) have burnt their fingers on it, so it's
not and easy matter. To prime the confusion, there are at least
two formulations of acoustic radiation pressure: one from Rayleigh
(which depends on non-linearity) and one due to Langevin (which
does not depend on it).
