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 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 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

Experimental Validation of the Model of Reverberation Time Prediction in a Room
Buildings, 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 ...
