Abstract: Based on the principle, a set of equations describing ultrasonic wave propagation in a dielectric crystal with charged dislocations has been derived. The linear dispersion relation has been derived, and the ultrasonic wave velocity and absorbance have been determined. In the case of the nonlinear ultrasonic wave, equations for its amplitude damping and phase variation have been obtained.
