✦ Synopsis

The analysis of the effect of attenuation on the time-averages for a plane travelling wave is presented. The barotropic equation of state is considered : i.e., acoustic heating is assumed to be negligible. The problem statement consists of calculating means in a finite region bounded by a transducer surface as well as by a perfectly absorbing surface, respectively. Although the simple wave approximation cannot be used throughout the field it is still valid near the perfect absorber. The result for radiation pressure is different from the conclusions given previously by Beyer and Livett, Emery and Leeman.
