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 The ideal state provides its Wil McCarthy () citizens with the tools to succeed Martin Marietta Corporation and the freedom to fail. I made this stuff up myself.
