Changes in acoustic and elastic properties of auricupride approach within the high temperature interval and close to an order-disorder phase transition have been discussed. Calculations of the phase velocities of purely transverse and longitudinal elastic waves, elastic moduli and Poisson's ratios based on elastic constants cij(T) of the crystal have been executed. Temperature changes of Grüneisen parameter along crystallographic directions ,  and  have been defined.
