Case study of measurements and computer modeling auralization results for medium‐sized multipurpose halls

This case study focuses on auralizations and their accuracy in modeling medium‐sized multipurpose halls (400‐600 seats). Within each hall, impulse response measurements were taken with drapes deployed and retracted. The same configurations were modeled in the room acoustics program 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. The modified and unmodified auralizations were then used to determine if any differences could be perceived in an informal listening evaluation. The auralizations and listening evaluation results are presented to better understand how to accurately auralize medium‐sized multipurpose halls.
