Prediction of energy decay in room impulse responses simulated with an image-source model
TL;DR: The technique presented in this work enables designers to undertake a preliminary analysis of a simulated reverberant environment without the need for time-consuming image-method simulations.

A beam tracing approach to acoustic modeling for interactive virtual environments
TL;DR: This work has developed a system that uses precomputed spatial subdivision and “beam tree” data structures to enable real-time acoustic modeling and auralization in interactive virtual environments and is using this system to develop interactive applications in which a user experiences a virtual environment immersively via simultaneous auralized and visualization.

The influence of reflections on auditorium acoustics
J.P.A. Lochner,J.F. Burger +1 more
TL;DR: In this article, the authors summarized the work carried out in this laboratory with the object of throwing more light on the interpretation, by the hearing mechanism, of reflection patterns in auditoria and the application of these principles to the design of auditoria.

A note on the importance of room cross-section in concert halls
TL;DR: In this paper, the spatial responsiveness of concert halls is identified as a desirable property of classical rectangular concert halls usually associated only with classical rectangular hall, and two halls, of classical and modern shape, are compared, and their echograms are subjected to a masking analysis based on the work of Seraphim.

Acoustics of the concert hall
TL;DR: In this paper, the energy relationship between early and late sound is found to be unexpectedly critical, and a new approach to the design of large concert halls is proposed. But this approach is not suitable for large-scale venues.
