Measurement System

ODEON has a powerful measurement system for acoustic measurements of real rooms. On top of ODEON itself, you will also need at least one speaker (in most cases omnidirectional) and a microphone. 

  • All editions have the measurements system
  • The Auditorium and Combined editions include the ability to make auralizations from measurements, as well as performing ambisonic measurements

Measurement system

ODEON can generate a sine sweep that is sent to the loudspeaker, then recorded in the room (or outside), and recalculates the recording 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.

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.
