摘要

A p-version wave envelope acoustic infinite element has been developed based on that of Astley et al. [1,2], but using different basis functions. This formulation does not require additional nodes for higher orders. Implementation of a practical method for interpolating field pressures is described, and the quality of interpolated field pressures is discussed relative to those obtained by Helmholtz integration in the frequency domain. Time-domain results for the element are also described.
