Impact of Temperature and Relative Humidity on Reverberation Time in a Reverberation Room

open access: yesBuildings, 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.

On the Modeling of Rectangular Geometries in Room Acoustic Simulations [PDF]

open access: yesIEEE/ACM Transactions on Audio, Speech, and Language Processing, 2015
This paper is concerned with an acoustical phenomenon called sweeping echo, which manifests itself in a room impulse response as a distinctive, continuous pitch increase. In this paper, it is shown that sweeping echoes are present (although to greatly varying degrees) in all perfectly rectangular rooms.

A round robin on room acoustical simulation and auralization [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2019
A round robin was conducted to evaluate the state of the art of room acoustic modeling software both in the physical and perceptual realms. The test was based on six acoustic scenes highlighting specific acoustic phenomena and for three complex, “real-world” spatial environments.

Computer Modeling of Barrel-Vaulted Sanctuary Exhibiting Flutter Echo with Comparison to Measurements

open access: yesAcoustics, 2020
Computer modeling in acoustics allows for the prediction of acoustical defects and the evaluation of potential remediations. In this article, computer modeling is applied to the case of a barrel-vaulted sanctuary whose architectural design and ...

Computing Room Acoustics Using 3D FDTD: A Cuda Approach. [PDF]

open access: yes, 2011
In seeking to model realistic room acoustics, direct numerical simulation can be employed. This paper presents 3D Finite Difference Time Domain schemes that incorporate losses at boundaries and due to the viscosity of air.

Benchmarking of finite-difference time-domain method and fast multipole boundary element method for room acoustics

open access: yes, 2022
Compared to geometrical acoustics, wave-based methods which solve the wave equation either in the time domain or in the frequency domain are known for their high accuracy.

Acoustic simulation of J.S. Bach’s Thomaskirche in 1723 and 1539

open access: yesActa Acustica, 2021
This paper investigates an early acoustical theory of Hope Bagenal about the Leipzig Thomaskirche, where J.S. Bach composed and conducted from 1723 to 1750. Bagenal predicted that the church had a shorter reverberation time than previously in Bach’s time

Study on Chinese Speech Intelligibility Under Different Low-Frequency Characteristics of Reverberation Time Using a Hybrid Method [PDF]

open access: yesArchives of Acoustics, 2023
Reverberation time (RT) is an important indicator of room acoustics, however, most studies focus on the mid-high frequency RT, and less on the low-frequency RT.
