Abstract :
In classical approach the instantaneous density of energy of plane acoustic waves depends on time and is not the integral of motion. We suggested the new approach for definition of the potential energy for which the instantaneous density of total energy of plane acoustic waves of various types does not depend on the time. These results are demonstrated for various types of plane acoustic waves in piezoelectric materials
