Abstract
EE Boost Inc. proposes to develop a new, fast and accurate hybrid wave-based method for acoustic simulation in large and complex environments. The hybrid method combines two efficient methods: the pseudo-spectral time-domain (PSTD) method and the enlarged cell technique (ECT). The PSTD method is extremely fast and accurate in computing fields in large cuboids without internal boundaries and interfaces. The ECT is geometrically flexible and can efficiently and accurately model complex boundaries. By removing the staircase errors, it is much more efficient than the conventional finite-difference time-domain (FDTD) method. The integration of the two complementary methods makes the simulation in large and complex environments still extremely fast without sacrificing accuracy. We have extensive experience with the advanced computational algorithms and are in an excellent position to develop such a fast and accurate method to meet the challenging needs of modern applications. The proposed method has some other good features. It is mathematically consistent, and is well suited to interactive simulation and hard acceleration.
