Wave velocities are dependent on the propagation direction in an anisotropic solid, and transverse waves can propagate with different wave velocities for certain propagation direction. The particle displacements are determined by propagating transverse wave mode. In the present work, the waves velocities and amplitudes of transverse waves were investigated when transverse wave with arbitrary direction of particle displacement propagate in anisotropic solids. Acoustic birefringence of bulk transverse wave propagating in  direction through silicon single crystal is studied. There are two transverse wave modes when the wave is applied along  direction in single crystal. Transverse wave is generated by using 20 MHz frequency transducer which delay line is 7 μs. For delicate control of vibration axis position, the  silicon single crystal is attached to rotary table with angle indicator. By pulse/echo method, the same transducer detects elastic transverse wave which is reflected and turns back from the opposite boundary of the sample.
