Abstract

Methods, systems, and computer readable media for utilizing adaptive rectangular decomposition (ARD) to perform head-related transfer function (HRTF) simulations are disclosed herein. According to one method, the method includes obtaining a mesh model representative of head and ear geometry of a listener entity and segmenting a simulation domain of the mesh model into a plurality of partitions. The method further includes conducting an ARD simulation on the plurality of partitions to generate simulated sound pressure signals within each of the plurality of partitions and processing the simulated sound pressure signals to generate at least one HRTF that is customized for the listener entity.
