In liquid 3He confined in aerogel, the 3He quasiparticles are scattered by random distribution of short-range potentials provided by the aerogel. We discuss the impurity effect on the dynamics of a p-wave order parameter on the basis of the linear response theory in the Keldysh formulation. Among the various types of order parameter fluctuations, we focus on the squashing mode which is known to couple to longitudinal sound.
