(1) Accoustic bombardment causes microcavitation in water

(2) Microcavitation creates nucleation sites in supercooled and/or
    supersaturated solutions.

With these observations I put forth the following theory: in addition to
providing more uniform cooling, accoustic refrigeration could result in a
smaller grain size upon freezing.  I.e., less damage at the cellular level.
However, the decibel levels required are such that macroscopic damage such as
cracking would likely increase.

Just my $0.02
