The history of the parabolic reflector as an acoustical amplifier is described, followed by an analysis of the theoretical amplification under various conditions. The complete theory is presented in an appendix. Measurements carried out confirm the theory. Examples illustrate the use of the reflector and methods to improve its performance. The application of the parabolic reflector for stereophonic recordings is discussed.
