A stationary model for the wind of asymptotic giant branch stars driven by acoustic waves is investigated. Through an averaging procedure, the effect of the sound waves on the flow can, in a linear approximation, be expressed in the form of a divergence of a pressure tensor as an extra term in the equation of motion. This greatly facilitates the solution of the equation of motion for the gas in such a stellar wind. Numerical calculations have been carried out to determine the structure of the stellar wind for a grid of asymptotic giant branch stars, with masses ranging from 0.75 to 3.0 solar mases. In most cases mass loss rates of the order of 10 to the -7th solar masses/yr to 10 to the -4th solar masses/yr can be obtained in a slowly accerating wind. The final velocity of the wind is generally of the order of some tens of kilometers per second. It is clear that the winds of stars on the asymptotic giant branch can be represented quite well by this simple model.
