Binaural Auralization of Room Acoustics with a Highly Scalable Wave-Based Acoustics Simulation

This paper presents a proposal of an efficient binaural room-acoustics auralization method, essential goal modeling. The method uses massively parallel wave-based solver based on dispersion-optimized explicit time-domain finite element (TD-FEM). hybrid technique first-order Ambisonics (FOA) and head-related transfer functions. encoding room impulse responses computed by that can model sound absorbers with complex-valued surface impedance. Details are given the novel procedure for computing expansion coefficients spherical harmonics composing FOA signal. report is first presenting able to simulate practical computational times using HPC cloud environment. A meeting problem classroom used, respectively, having 35 million degrees freedom (DOF) 100 DOF, test performance up 6144 CPU cores. Then, potential proposed demonstrated via auditorium acoustics simulation 5 kHz 750,000,000 DOFs. Room-acoustics performed two treatment scenarios evaluations use signal, response, four acoustical parameters. showed enables within 13,000 s
