Abstract
Sound propagation in superfluid 3He in aerogel is studied on the basis of a two-fluid model taking into account the effect by the drag force due to collisions between 3He-quasiparticles and aerogel molecules. The drag force plays a role of frictional force between the aerogel and the normal-fluid component. In local equilibrium, they move together in accordance with McKenna
