Modeling the Transient Acoustic Field Radiated by a Loudspeaker
This research concentrates on determining the transient acoustic field of a loudspeaker by applying uncoupled finite-element and boundary-element methods. The well-known problem of instability when working in the time domain was avoided by using a Burton–Miller type integral equation formulation. The accuracy of the results shows that this approach is well suited for modeling loudspeakers. Stable results were obtained in all cases and they were reasonably accurate when the time step was smaller than or equal to the experimental sampling rate. Two examples of insights are provided: differing decay rates of various loudspeaker components, and the presence of the acoustic center.
