On the Spatial Characteristics of a Circular Piston
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2015, Vol 12, Issue 1
Abstract
In this paper a theoretical overview of existing and well known mathematical techniques for calculating the sound pressure level (SPL) created by a circular piston in its near and far field is presented. A unified approach for explaining the acoustic transducers’ spatial characteristics is proposed. The polar responses and the frequency responses of given circular pistons are modeled and visualized by means of Matlab®-based scripts. Finally some experimental data are presented. Conclusions with practical value have been made. A few topics for future works are considered.
