We address the challenge of acoustic simulations in three-dimensional (3D) virtual rooms
with parametric source positions, which have applications in virtual/augmented reality, game …

In this paper we describe the research and development activities in the Center for Efficient
Exascale Discretization within the US Exascale Computing Project, targeting state-of-the-art …

2. Methods We take a data-free approach where only the underlying physics is included in
the training and their residual minimized through the loss function, allowing insights into how …

The discontinuous Galerkin (DG) method is widely being used to solve hyperbolic partial
differential equations (PDEs) due to its ability to provide high-order accurate solutions in …

In outdoor acoustics, the calculations of sound propagating in air can be computationally
heavy if the domain is chosen large enough for the sound waves to decay. The …

Model order reduction techniques significantly reduce the computational time when
performing accurate room acoustic simulations with numerical methods that inherently …

The time domain linear sampling method (TD-LSM) solves inverse scattering problems
using time domain data by creating an indicator function for the support of the unknown …

ABSTRACT Room Impulse Response (IR) captures the characteristics of the associated
room and is affected by geometry, boundary materials, and objects within the room. Being …

The software and hardware landscape of high performance computing is expanding faster
than computational scientists can take advantage of new frameworks and platforms. In an …

The study of room acoustics has traditionally been of interest in architectural planning and
design. With the spread of virtual-and augmented-reality technology, room-acoustic …
