CYLINDER IN THE INTERMEDIATE
AND FAR ZONES OF AN ULTRASONIC FIELD

The field of an acoustic transducer in the region of detection 
of an ultrasonic wave beyond the near zone is considered as applied 
to nondestructive check of the surface density of foil-film materials 
by the method of their irradiation with an ultrasonic wave through 
air. The results obtained refine the existing concept of the pressure 
distribution on the surface of an acoustic cylinder in the intermediate 
and far zones of the field.
