Abstract : With the great demand for extending the ranges of active sonar on ships, analysis into lower frequency transmission and better power transfer is of great importance. Wave theory is used to analyze a steel horn and its effect on impedance, frequency response, and directivity of an electro-mechanical transducer. The horn was found to make the transducer a broader band device but only a small gain was observed in power output.
