HIGH FREQUENCY ROOM RESPONSES: acoustic design and the control of stereophonic image quality R. Walker, B.Sc.(Eng.), C.Eng., F.I.O.A., M.I.E.E.

Summary Aspects of mid and high frequency acoustic design are described, mainly in the context of relatively small rooms. The factors affecting the design and some of the difficulties which may be encountered are also discussed. The primary means of evaluating the quality of reproduced sound is the studio control room (and its associated equipment). This Report is written primarily in terms of the design of control rooms, but is directly applicable to other small spaces and, to a lesser extent, to larger spaces.
