Ultrasonic attenuation measurements have been firstly performed for a large single crystal of PrOs 4 Sb 12 with the dimensions of 5:97 Γ 0:6 Γ 0:6 mm 3 . Remarkable frequency dependence around 20-40 K has been observed in the elastic constant and attenuation coefficient of the longitudinal C 11 mode
