Propagation of volumetric acoustical waves (VAW) and surface acoustical waves (SAW) was investigated in a $Bi_2WO_6$ crystal. Values of the moduli of elasticity $C_{22}$ and $C_{36}$ are acquired along with the value for the pseudo-modulus $d_{24}$. The anisotropy of the speeds and losses to conversion is investigated for SAW excited in the [010] plane of the crystal using an interdigital converter. The possibility of using natural plates of the crystal as a VAW converter is investigated.
