Pressure Differences Above Surface<br />

• <strong>Acoustic</strong> wave, during<br />

propagation above material<br />

surface, arises quickly-changing<br />

changing<br />

zones of increasing and<br />

decreasing pressure.<br />

• Accordingly Boucher hypothesis,<br />

in the increasing pressure zones<br />

drying speed do not decreases,<br />

while in the decreasing pressure<br />

zones arises additional effect of<br />
