Ultrasonic measurements were performed on a fci Zn-Mg-Y quasicrystal and
on the related parent compound 
. Absolute values of both the longitudinal
and the transverse sound velocities as well as their temperature dependence
were determined. The temperature dependence of the quasicrystal sound velocity
in the millikelvin temperature range is very similar to the logarithmic behaviour
observed for amorphous materials.
