Abstract
This paper presents a method of calculating the pressure at any point emerging from a plane piston of polygonal shape in an infinite baffle. This is achieved by calculation of the impulse response as a time-stepped function, and considering the effect of each edge of the polygon in turn. The pressure is found from the convolution of this function with the time derivative of the piston velocity multiplied by the density of the propagation medium. Calculated pressure fields are shown for both a series of sources shaped as regular polygons, and for a source with an irregular shape. It is shown that the approach could be useful for the calculation of radiated fields from sources of arbitrary shape.
