Electron-strain interaction in CeAs has been investigated by ultrasonic measurements. Elastic softening reflecting the crystalline field state of Γ7(0 K) and Γ8 (160 K) has been found in the C44 mode. The character of the acoustic de Haas-van Alphen (dHvA) defect on the β hole surface is discussed.
