• The attenuation (amplification) coefficient of the acoustic waves interacting with conduction electrons in an anisotropic medium is obtained with the aid of the energy conservation law. The resultant formula is applicable to onaxis as well as off-axis attenuation of the sound and predicts an effect of the longitudinal magnetic field on field on acoustic amplification. The formula is extended to the case of multiple cariers, e.g., electrons and holes, or carriers from valleys, where its dependence on the conductivity tensor differs from that in the case of deformation potential coupling.
