Diverse acoustical modules have identical outward appearance. A series of modules each has an unobtrusive acoustically transparent surface, each module providing a different acoustical functionality while each bears a common outward appearance. Therefore, an acoustical environment can be created specifically suited for the particular application, but devoid of any distracting differences of appearance between the respective absorbers, reflectors, and diffusers that are employed to create the aesthetic appearance. One manner of installation can include a grid structure suspended from the existing ceiling and allowing each module to be removably installed in a space having a desired shape such as a square or rectangle. Alternatively, the different acoustical treatment modules can be directly surface mounted to a ceiling or wall, preferably in a manner permitting easy removal for servicing or replacing due to damage or changing acoustical characteristics.
