Simulation of a coupled room scenario based on geometrical acoustics simulation models

Journal of the Acoustical Society of America, 2019
As part of the most recent room acoustical simulation round robin, a coupled room scenario, consisting of a laboratory room and a reverberation chamber, is investigated.

Numerical Geometric Acoustics

2021
Sound propagation in air is accurately described by a small perturbation of the ambient pressure away from a quiescent state. This is the realm of linear acoustics, where the propagation of a time-harmonic wave can be modeled using the Helmholtz equation.

Effects of Geometrical Acoustics Model Simplification on Binaural Reverberation

IEEE Transactions on Audio, Speech, and Language Processing
Virtual reverberation rendering typically requires detailed information about room geometry and surface acoustic characteristics. While comprehensive modeling approaches can account for all aspects of an acoustic environment, they often incur high ...

Underwater acoustic sensing using the geometric phase

The Journal of the Acoustical Society of America, 2023
We present a sensing modality using the geometric phase of acoustic waves propagating in an underwater environment. We experimentally investigate the effect of scattering by a small subwavelength perturbation on a flat submerged surface. We represent the state of an acoustic field in the unperturbed and perturbed cases as multidimensional vectors.

Multiresolution geometrical-acoustics modeling

The Journal of the Acoustical Society of America, 2008
Geometrical-acoustics (GA) modeling techniques assume that surfaces are large relative to the wavelengths of interest. For a given scenario, practitioners typically create a single 3D model with large, flat surfaces that satisfy the assumption over a broad range of frequencies. Such geometric approximations lead to errors in the spatial distribution of

Web-based geometric acoustic simulator

Proceedings of the 23rd International ACM Conference on 3D Web Technology, 2018
Geometric acoustics is one of the most commonly used techniques for exploring what a virtual environment sounds like. These methods allow the user to place a sound source and receiver in a space and compute how the space influences what the receiver hears. These simulation methods are well-known, but most are proprietary or difficult to implement.

Lines for listening: on Gustave Lyon’s geometrical approach to acoustics

Journal of Architecture, 2018
Based on Gustave Lyon’s archival material and the understanding of his practice as an acoustical consultant, this contribution aims to show how the adoption of a scientific method offered a broader insight into the cultural architectural debate of the ...
