Die neuesten Ergebnisse der Ultraschall-Forschung in Anwe...
Theoretical considerations and experimental references are introduced to show that the science of supersonics is not so much a matter of the inaudible sounds themselves as essentially of their practical applications in the new "mechanical high-frequency techniques": these lie predomin antly in liquids and solids. Apart from underwater communications, one of the oldest fields of application for ultrasonics is the ...
