Sound transmission experiments from an impulsive source near rigid wedge

Experimental sound transmissions in air from a park source to a small microphone were studied near rigid wedges. Two types of experiments were carried out. The first experiments were transmissions at 12° and 52° wedge respectively. The Biot-Tolstoy exact wedge solution was used to calculate the theoretical impulse responses. At the 12° and 52° wedge, the solution gives a finite set of images and a diffraction arrival. Theory and experiments matched. The second type of experiments measured the image reflection as the reflection point was moved to the edge of a half-plane and tested Kirchhoff solution. They confirmed the correctness of the exact wedge solution and the incorrectness of the Trorey solution.
