Abstract:
In the present study the acoustic field around rigid wedges is investigated. The acoustic field consists of diffraction contributions (from the edge) and of geometrical acoustics contributions (the incident signal and signals reflected on the wedge faces). A new depiction, called the polarity plot, is proposed that depicts the polarity of the diffracted impulse response, as well as the number of the geometrical acoustics contributions around a given wedge. Based on the observed patterns of the polarity plots, a set of measurements around a wedge is described which (if experimentally feasible) could be used in order to determine the wedge angle.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
Wedges
Consider using a wedge to lift a heavy slab. Here, the wedge functions by converting the applied force into a much larger force directed almost perpendicular to the initial force. This...
Two-Dimensional Force System: Problem Solving
The first step to solving a two-dimensional force system problem is to draw a free-body diagram of the object under consideration. This diagram helps identify all the external forces acting on the object, including their...
