The sound attenuation due to collisions in superfluid $sup 3$He is studied, using for the collision integral a simplifying ansatz which satisfies conservation laws. In the zero-sound regime, attenuation and velocity are fairly frequency independent; this supports the idea that collisions can be accounted by a mere background in sound attenuation. In the first-sound regime, the viscosity tensor is studied (in the A phase) and its low-temperature behavior investigated. (AIP)
