ISO 3382 sets the standard procedure for measuring the acoustics of a room. With ODEON, you can both simulate and measure a room’s acoustics in accordance to the standard. Simulations allow you to predict acoustics using ideal mathematics and algorithms, while measurements are obviously more realistic and do include waves’ phase. Impulse responses can be easily loaded into ODEON in WAV format, and ODEON will work around imperfections in the recorded response via onset detection, truncation and compensation. The video also shows example cases with an auditorium and a cathedral.
Presented by by Claus Lynge Christensen at ISRA 2013 Conference in Toronto, Canada.
