The high end pro theaters absolutely use the coffered ceiling as part of the acoustic plan. Breaking up hard flat surfaces is a good thing acoustically. Also they will often conceal acoustic treatments in the rectangular spaces between the coffer ridges.
高端专业剧院绝对使用格子天花板作为声学计划的一部分。 分解坚硬的平面在声学上是一件好事。 此外,它们通常会在箱脊之间的矩形空间中隐藏声学处理 (conceal acoustic treatments 的结构或材料 - 我加的说明)。
