ODEON
Predicts how a room will sound before it's ever built
What it is
About ODEON
ODEON uses ray-tracing and image-source modelling to simulate reverberation time, speech intelligibility, and other acoustic parameters within 3D room models, commonly built from imported CAD/BIM geometry. It's used by consultants designing concert halls, classrooms, offices, and other spaces where acoustic performance matters, and to check compliance against standards such as Building Bulletin 93 (BB93) or Part E of UK Building Regulations.
What you can do with it
Capabilities
Model 3D room geometry and material acoustic properties
Simulate reverberation time, clarity, and speech intelligibility (STI)
Auralise a space — listen to a simulated room before construction
Test design changes against acoustic targets
Check compliance with standards like BB93 or Part E
How to learn it
Learning Resources
ODEON's official manual and tutorial videos
ODEON training courses run by ODEON A/S
Institute of Acoustics (IOA) training and conference materials
Practise by modelling a simple known room and comparing to measured RT60
Pro Tip
Garbage-in-garbage-out applies hard here — inaccurate absorption coefficients for materials will wreck your prediction accuracy more than any settings tweak.
