Tubular and Exponential Horn Acoustic Couplers for Monotone Operation of Electrodynamic Drivers

Abstract

The purpose of this project was to investigate the properties of tubular and exponential horn couplers designed to produce pc loading. The theory for design of tubular couplers is reviewed, and extended to exponential horns. Computer programs to perform the design calculations are included. in Appendix A. Experimental results were obtained for tubular and exponential horn couplers which support the theoretical results.
