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

An Acoustic Reconstruction of the House of Commons, c. 1820–1834

Acoustics, 2023
This paper presents an acoustic reconstruction of the UK House of Commons between c. 1820 and 1834. Focusing on a historically important site where political decisions were debated over the centuries, we aim to simulate and present the intangible ...

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

, 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

Buildings, 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.

Scaling of Huygens-front speedup in weakly random media [PDF]

, 2007
Front propagation described by Huygens' principle is a fundamental mechanism of spatial spreading of a property or an effect, occurring in optics, acoustics, ecology and combustion.

Shock wave focusing using geometrical shock dynamics [PDF]

, 1997
A finite-difference numerical method for geometrical shock dynamics has been developed based on the analogy between the nonlinear ray equations and the supersonic potential equation.

The image edge model

Acta Acustica, 2021
Noise from traffic, industry and neighborhood is a prominent feature in urban environments. In these environments, sound reaches receiver points through reflections and diffractions.

Directivity patterns of laser-generated sound in solids: Effects of optical and thermal parameters [PDF]

, 2014
In the present paper, directivity patterns of laser-generated sound in solids are investigated theoretically. Two main approaches to the calculation of directivity patterns of laser-generated sound are discussed for the most important case of thermo ...
