The Brillouin scattering tensers and the stiffening Christoffel equations in (100), (010), and (001) planes of C2v point group crystals are obtained at arbitery wave vector directions. Based on these results, all the independent elastic and piezoelectric constants of LBO crystals are determined by means of Brillouin scattering , and the sound velocity anisotropic curves in the three planes are also shown
