Reflection, diffraction, and higher order diffractions from a finite width wedge construction on an effectively infinite plane were studied experimentally and theoretically. The construction consisted of a 12.6‐cm‐width angle iron on dry wall boa

The reflections of transient pressure signals from hard (perfectly reflecting) finite width plane facets have been studied theoretically and experimentally. The experiments and theory used point sources, and sound pressures were observed in the specu

Continental boundaries have a shallow sloping bottom that changes to a steeper slope. Our laboratory acoustic models (simulations) have (1) a 11° slope that changes to a 50.5° slope and (2) a 35° slope change to a 59° slope. The surface and botto

The higher‐order diffractions of transient pressure signal from a combination of hard finite facet wedge of 45 deg and an infinite plane have been studied experimentally and theoretically. Experiments used a spark point source with a separated rece

The experiments were made in an ideal air waveguide having Sheetrock (hard) boundaries. Transmissions of a signal were from a source to a pair of receivers. Matched filter and deconvolution procedures were tested. Matched filters were computed for tr

Experimental sound transmissions in air from a spark source to a small microphone were made near rigid wedges. Two types of experiments were made. The first experiments were transmissions within an approximately 12° wedge and a 52° wedge. The Biot

Transmissions in an ideal wedge waveguide in air are described. The walls are rigid. The Biot‐Tolstoy exact wedge solution is used. The diffraction arrival from the apex is not present. Signals transmitted in a waveguide are distorted by the multip

Experimental measurements that were made in an ideal waveguide in air are reported. The experiments confirmed the theoretical technique. Signals transmitted in a waveguide are distorted by the multiple arrivals. A waveguide matched filter has an impu
