This paper briefly outlines the development of control room acoustics from the earliest inception, through phases of monophonic, two-channel stereophonic and, most recently, multichannel sound. It concentrates especially on the control of early reflections from the boundary surfaces of the room and the detrimental effects of those reflections on sound stage imaging. Design methodologies are described that allow the shapes of the room boundaries to be so arranged that the early reflected sound energy does not return to the principal listener’s position until after an initial time gap. Results are presented from measurements on a conventional control room, a stereophonic room designed with minimum early reflections and from a multichannel room. Though the discussion is presented in terms of control room design, the simplified principles for multichannel design are also applicable directly to domestic listening spaces.
