Surface diffusion coefficients for room acoustics : free-field measures [PDF]

open access: yes, 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.

Modelling and directionally encoding the acoustics of a room [PDF]

open access: yes, 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.

Using Virtual Reality to Evaluate the Impact of Room Acoustics on Cognitive Performance and Well-Being

open access: yesFrontiers in Virtual Reality, 2021
Irrelevant ambient noise can have profound effects on human performance and wellbeing. Acoustic interventions (e.g., installation of sound absorbing materials) that reduce intelligible noise (i.e., sound unrelated to the relevant speech, including noise ...

Experimental Validation of the Model of Reverberation Time Prediction in a Room

open access: yesBuildings, 2022
It is well known that the uncertainty of input data has a great influence on the accuracy of room acoustics simulations. The aforementioned accuracy is significantly influenced by the selection of the acoustic properties of room-delimiting materials ...

Image method for efficiently simulating small‐room acoustics

open access: yes, 1976
Image methods are commonly used for the analysis of the acoustic properties of enclosures. In this paper we discuss the theoretical and practical use of image techniques for simulating, on a digital computer, the impulse response between two points in a ...

The KW-boundary hybrid digital waveguide mesh for room acoustics applications [PDF]

open access: yes, 2007
The digital waveguide mesh is a discrete-time simulation used to model acoustic wave propagation through a bounded medium. It can be applied to the simulation of the acoustics of rooms through the generation of impulse responses suitable for auralization

Integrating Real-Time Room Acoustics Simulation into a CAD Modeling Software to Enhance the Architectural Design Process

open access: yesBuildings, 2014
For architects, real-time 3D visual rendering of CAD-models is a valuable tool. The architect usually perceives the visual appearance of the building interior in a natural and realistic way during the design process.

Improved Room Acoustics Quality in Meeting Rooms: Investigation on the Optimal Configurations of Sound-Absorptive and Sound-Diffusive Panels

open access: yesAcoustics, 2020
This work deals with the improvement of the room acoustic quality of two medium sized meeting rooms through the investigation of the optimal placement of absorption and diffusive panels on the walls and ceiling.
