SoundRad - 2D room acoustic modeling utility

*** Please note: This software is OSX only ***

Small program for teaching various geometric room acoustic modeling techniques in 2D. The incorporated modeling techniques are:


  • Image source method
  • Ray tracing
  • Acoustic radiance transfer, i.e., a radiosity method with arbitrary reflection properties


To help people understand the acoustic radiance transfer method, there is a possibility to visualize and study the required acoustic BRDFs, i.e. the acoustic bidirectional reflectance distribution functions that describe the acoustic behavior of materials.

In addition there is a very simple 2D modeling tool for model creation so that you can try these visualizations in your own 2D geometries.
