Designing a desirable medium‐sized multipurpose hall using ODEON Free

This presentation focuses on using the room acoustics program ODEON for modeling a desirable medium‐sized multipurpose hall (400‐600 seats). A sampling of medium‐sized halls was taken and impulse response measurements were conducted with drapes deployed and retracted. In each hall, the same configurations were modeled in ODEON. Acoustical parameters, such as T20, T30, C50, C80, were used to check the agreement of the model to the measurements. A systematic approach was then used to adjust model parameters to match the real‐world measurements. These results and modifications are presented to better understand how to accurately model and design medium‐sized multipurpose halls.
