Fast multipole accelerated boundary element methods for room acoustics [PDF]
Journal of the Acoustical Society of America, 2021 Direct and indirect boundary element methods, accelerated via the fast multipole method, are applied to numerical simulation of room acoustics for rooms of volume ∼150 m3 and frequencies up to 5 kHz on a workstation. As the parameter kD (wavenumber times

A Universal Deep Room Acoustics Estimator [PDF]
IEEE Workshop on Applications of Signal Processing to Audio and Acoustics, 2021 Speech audio quality is subject to degradation caused by an acoustic environment and isotropic ambient and point noises. The environment can lead to decreased speech intelligibility and loss of focus and attention by the listener.

Issues for computer modelling of room acoustics in non-concert hall settings [PDF]
, 2005 The basic principle of common room acoustics computer models is the energy-based geometrical room acoustics theory. The energy-based calculation relies on the averaging effect provided when there are many reflections from many different directions, which

Real Acoustic Fields: An Audio-Visual Room Acoustics Dataset and Benchmark [PDF]
Computer Vision and Pattern RecognitionWe present a new dataset called Real Acoustic Fields (RAF) that captures real acoustic room data from multiple modali-ties. The dataset includes high-quality and densely captured room impulse response data paired with multi-view images, and precise 6DoF ...

An archaeoacoustic study on shape: the case study of the Iffland Theatre’s history (1802–1817)
Acta Acustica, 2023 Previous studies have discussed six pre-Sabine quantifiable guidelines employed in room acoustic design: voice directivity, audience rake, “echo theory”, stage acoustics, reverberation, and length, width, and height ratios.

Modelling and directionally encoding the acoustics of a room [PDF]
, 1998 Geometrical methods are often used to model the acoustic properties of a room, but are valid only for high frequencies. At low frequencies. diffraction and the effects of room modes cannot be neglected.

Surface diffusion coefficients for room acoustics : free-field measures [PDF]
, 2000 A surface diffusion coefficient is needed in room acoustics to enable the quality of diffusing surfaces to be evaluated. It may also facilitate more accurate geometric room acoustic models.
