Acoustic description:
Sound in this space quickly drops and is deadened by the same thick walls that keep out sound. Sound drops 30db in 0.5s, almost as quickly as it arrived, and it continues to drop as quickly until it is at the level of its usual background noise. This keeps echo and residual hum to a minimum, probably an intentional move by the designer of the space, since overlapping sounds of dancers moving across the floor would detract from the more visual qualities of it.
