Abstract The ultrasonic attenuation of a range of commercial lead—silicate glasses has been studied over the temperature range 4.2 to 360 K. Measurements of shear-wave ultrasonic attenuation,A, over the frequency range 5 to 50 MHz have revealed peaks in the attenuation below room temperature and these are interpreted in terms of the resonant movement of oxygen ions in the silica networks. In some cases the effects of the peaks are seen to extend to room temperature in some of these glasses. Frequency dependence of the attenuation,A, can be fitted to a relation of the formA ∝F N , whereF is the frequency andN is a constant. Shear-wave velocities are also measured to aid characterization of the glasses.
