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

Impact of Temperature and Relative Humidity on Reverberation Time in a Reverberation Room
Buildings, 2022 Changes in acoustic parameters measured in a room may depend on the location and orientation of the sound source and microphones or on the reverberation conditions of the room.

The R3VIVAL Dataset: Repository of Room Responses and 360 Videos of a Variable Acoustics Lab
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2023 This paper presents a dataset of spatial room impulse responses (SRIRs) and 360° stereoscopic video captures of a variable acoustics laboratory. A total of 34 source positions are measured with 8 different acoustic panel configurations, resulting in a ...

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.

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.

The room acoustic rendering equation [PDF]
The Journal of the Acoustical Society of America, 2007 An integral equation generalizing a variety of known geometrical room acoustics modeling algorithms is presented. The formulation of the room acoustic rendering equation is adopted from computer graphics. Based on the room acoustic rendering equation, an acoustic radiance transfer method, which can handle both diffuse and nondiffuse reflections, is ...
