It is possible. If you know both sound speeds (longitudinal and transversal waves) and density, you can calculate all elastic parameters (Lame constants) of the material.

There are many possibilities to do it. Ultrasonic refractometry is one of them, spectroscopy methods, combination of acoustical and optical methods (proposed by Bergmann), etc.

We have an application note on the subject that explains the basic procedure. Please see the link below. As Mr. Bicz write, you need to measure longitudinal and shear (transverse) wave velocity, and know the density of the material, and enter those values into the formula in the app note.
