The room-temperature attenuation for longitudinal acoustic waves propagating in the c direction in high-purity CdS has been measured from 0.1 to 0.6 GHz. At 0.5 GHz the attenuation is 46 dB/cm (tanδ=0.0015). From the observed attenuation corrected for phonon-electron contributions and a lattice loss theory of Woodruff and Ehrenreich, a Grüneisen parameter of ± 1.51 is calculated. An alternate method of calculating the Grüneisen parameter by using the pressure dependence of the elastic constants gives a Grüneisen parameter of -1.37.
