A dynamic acoustic system for use in connection with an indoor environment includes a plurality of elongated acoustic bars and a controller operably to each of the elongated acoustic bars. Each of the bars is operably coupled to a ceiling member of the indoor environment and includes an upper portion, a lower portion, a plurality of side surfaces extending between the upper and lower portions, an interior region at least partially defined by the upper portion, the lower portion, and the plurality of side surfaces, and at least one movable element movable between first and second positions. The controller selectively controls operation of the at least one movable element of a desired number of the plurality of elongated acoustic bars to alter an environmental characteristic of the indoor environment.
