Acoustical measurements were taken in three traditional theaters integrated with Chinese gardens. Each theater consisted of a pavilion-like stage inside a courtyard surrounded by covered galleries, walls, or rock piles. The courtyard was generally rectangular in shape. Water, rocks, bridges, walls, and vegetation made the theater space rather irregular. All measurements were taken when the floors were unoccupied and without seats. Analysis showed an average strength G of 4.7 dB, an average early decay time EDT of 0.74 s, and an average early support STE of `9.3 dB.
