Abstract
Systems and methods for acoustic simulation in accordance with embodiments of the invention are illustrated. One embodiment includes a method for simulating acoustic responses, including obtaining a digital model of an object, calculating a plurality of vibrational modes of the object, conflating the plurality of vibrational modes into a plurality of chords, where each chord includes a subset of the plurality of vibrational modes, calculating, for each chord, a chord sound field in the time domain, where the chord sound field describes acoustic pressure surrounding the object when the object oscillates in accordance with the subset of the plurality of vibrational modes, deconflating each chord sound field into a plurality of modal sound fields, where each modal sound field describes acoustic pressure surrounding the object when the object oscillates in accordance with a single vibrational mode, and storing each modal sound field in a far-field acoustic transfer (FFAT) map.
