The effects related with formation of induced anisotropy in natural-isotropic media, have been studied already for a long time. These phenomena interest scientists first of all due to a rare opportunity of control of artificial anisotropy of media, and also due to an opportunity of the energy transfer to a propagating acoustic or an electromagnetic wave. The idea of the nonlinear interaction of an acoustic and rotating electric field for the observation of parametrical electro-acoustic effects in crystals belongs to V.N Belyi and B.B. Sevruk, and has been ascertained more than 20 years ago [1], [2]. Then this idea has being developed by physicists of the Gomel State University [3]-[8] where F.I. Fedorov, B.V. Bokut', and A.N. Serdyukov [9]-[10] created a scientific school in the field of optics and acoustics. Until the present time the opportunity of suppression of absorption of ultrasound by rotating an electric field and amplification of ultrasonic waves in a crystal in conditions of resonant interaction of an electric field with ultrasound [11]-[14] has been predicted. In this case, media with the induced rotating spatially homogeneous acoustic anisotropy represent an acoustic analogue of spatially periodic media, showing the effects characteristic for the last.
