Overhead stage canopies composed of many panels suspended under ceiling provide proper acoustic field in concert halls and auditoria. The purpose of using these structures is adequate direction and partial dispersion of sound reflected from them. Frequency range of sound reflected from flat panels closely depends on their shape, size and configuration. It is often too narrow and therefore insufficient for the proper sound of the interior. Mutual dependence of the lower and upper frequency limit of sound transmission requires the search for other ways to improve these structures. The paper proposes some solutions concerning spatial structures which have not been yet defined. An attempt was made to determine the useful frequency band of sound transmitted through such reflective structures.
