| Abstract | The use of three-axis energy density sensors for controlling the sound field within a rigid walled enclosure is investigated numerically. It is shown that energy density sensors perform as well as, if not better than, an equivalent number of microphones. The effect on control performance using multiple energy density sensors is also investigated as is the effect of multiple control sources. The control mechanisms that occur when using energy density sensors with multiple control sources are analysed, and it is shown that the control mechanism moves from modal control to modal rearrangement as the number of control sources is increased. In doing so, the control becomes more local to the sensors. The zone of local control around the energy density sensors is measured and it is shown that the zone of control is similar in size to that in a diffuse field. B.S. Cazzolato & C.H. Hansen IJAV 3 |
