A reorientation of the ferroelectric domains under an action of ultrasound in LiNbO3 is observed for the first time. The involvement of the ferroelectric domain boundaries is experimentally identified by the analysis of X-ray reflection and crystal etching. The reorientation of the domains takes place under acoustic deformation of the order of 1E-5 in megahertz frequency range.
