By enclosing the propeller of a submersible vehicle in a rigid cylindrical duct it is possible to exercise control over the discrete frequency noise produced. The applicable portions of spinning mode theory are reviewed and its application to submersible vehicles is illustrated with numerical examples. (Author)
