Hybrid image/energy approach for acoustical predictions of industrial rooms

André L'espérance

Abstract


A hybrid approach based on geometry acoustics and on energy acoustics was developed for acoustical prediction computation. A user-friendly interface was also developed to facilitate the use of this model. Observations reveal that the results obtained from this model were similar to the ones obtained from accurate methods.
