The infrared divergence response theory is applied to reorientational relaxation process of OH- in KCl: OH to study the behaviour of low temperature ultrasonic absorption in this system. Our calculation results showed that the thermally activated relaxation process makes the main contribution to the ultrasonic absorption for T>4.5K; as for T<4.5K, the tunneling relaxation process can not been neglected.
