This work was undertaken to learn reasons for the behavior of the barrel-stave acoustic radiator, operating in a condition devoid of all pressure release. This source configuration is most difficult to deal with because it has a shape which is mathematically awkward. Its height is small in comparison with the diameter, thus making cylindrical coordinates of little value. Admittedly, the cylindrical radiator does not closely approximate a sphere, but a circumscribing sphere radius the same as the source radius has distinct advantages. The radiation from a spherical source with an arbitrary surface velocity distribution is easily handled analytically. It is this fact that makes the present approach attractive. Also, some computer results provide plausible explanations for unexpected phenomena that occur in tests with these radiators. In the interest of completeness, the theory of the spherical radiator will be presented. Applications of this theory to the special problem at hand indicate what can be expected from the method. Consideration of different frequencies and different velocity distributions provide conclusions that are very useful in the basic design process and in the process of modifying the performance of existing designs.
