    Abstract

    The sound reproduced in a room by a conventional audio system is modified because of the acoustic response of the room. In this paper a theoreticalstudy based on computer simulations for the synthesis of a desired sound field in a room is presented. The optimal solution in a continuous region that covers almost the entire volume of the room has been obtained with the least-square approximation. It is shown that the synthesis of travelling waves in a certain direction is possible at frequencies up to 320 Hz in a room with dimensions 2.9x3.6x2.5 m using 32 loudspeakers. If waves travelling in any direction should be obtained 56 loudspeakers will berequired.
