Lectures and Research

Lectures and other videos about the more scientific background within room acoustics and room acoustic simulations.

Ray tracing and hybrid methods in room acoustics

Simulations in the Odeon software are based on hybrid methods combining ray tracing, image source modelling, and secondary source modelling. The video describes how ray tracing works and has been improved with vector based scattering; how the image source method works and can create a reflectogram; and how the hybrid method combines ray tracing and secondary source modelling for late reflections. Finally, it is shown how particle tracing works as an extension of raytracing as an efficient tool to estimate the reverberation time in a room.

Sound Distribution in Some Organic Geometries

This video presents work made by Maya Bartur, Marzieh Birjandian, Johanna Huang and Christos Sazos in their master thesis at Design Research Laboratory | Architectural Association School of Architecture, London, UK (2011/2012). ODEON has been used in the project for visually describing sound distribution in some very organic geometries.
