Measurement System

ODEON has a powerful measurement system for measurements of real rooms. On top of ODEON itself, you will also need at least one speaker (in most cases omnidirectional) and a microphone. ODEON generates a sweep for the speaker, that is recorded in the room (or outside) and then recalculated into an impulse response. The Sine Sweep Method is the most effective way of measuring room acoustics while suppressing background noise, both from other sounds and the electronics themselves.

  • All editions have the measurements system
  • The Auditorium and Combined editions include the ability to make auralisations from measurements

Measuring System in ODEON

(NOTE: THIS IS NOT THE NEWEST MEASURING SYSTEM. Updated video being made, but the basics are the same.) 

A comprehensive introductory video on the ODEON Measuring system by Claus Lynge Christensen: How to make a measurement, how to process it and how to import measurement results to simulations.

Two Step Sound Source Calibration

The two step calibration in ODEON makes it easier AND safer to calibrate the measurement system by adding a second step to the calibration in the laboratory and repeating this second step in-situ, just before performing the measurements.

 

Onset and Truncation Time

Although ODEON automatically detects the onset and truncation times in an impulse response, it is often desirable to have manual control on these parameters. The measuring system in ODEON 13 allows such versatility.
