Abstract
Previous research on the quiet zones created in the free space, using multiple control sources and error microphones equally located in two parallel lines or in two parallel planes, demonstrated that there exists a range of optimal spacing for the control sources and error microphones. With the optimal arrangement, the largest area of quiet zone can be created with the least increase of total power output. This range for the optimal spacing is related to the configuration of the control system and the wavelength of the noise. The effectiveness of the optimally arranged control system to broadband noise is investigated in this paper. The results from both numerical simulation and experiment show that a control system optimally arranged for a particular frequency will be effective not only to the noise at the frequency, but also to that within a frequency band specified in this paper.
