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.
