We present results on acoustic drying of wood (pine). 
By use of a tomograph, we obtained the distribution of moisture in 
the cross section of a specimen before and after acoustic action exerted 
on it. It is found that in the direction of the normal to the annual 
rings this action is not monotonic, but rather it varies periodically. 
Affected by an acoustic field, moisture flows intensely from the early 
to the late zone of an annual ring.
