Reverberation rooms are a considerable investment and often perform worse than hoped for when first constructed. Modifications to a room are costly due to materials, building, and downtime. Hence, there is a need to use simulation to predict the effect of modifications prior to that investment. Rather than relying on time-consuming trial-and-error approaches, a finite element simulation model is developed and tuned to match the low frequency behavior of an existing medium sized reverberation room. The simulation was checked by comparing to the measured reverberation time and the standard deviation of sound pressure level. The model and its validation are detailed. Using this model, the effect of room modifications such as diffuser geometry, material, size, and placement are considered.
