N2 - During the design of transducers placement for an active noise control system, current optimization methods need to predetermine the error sensors placement, which makes the secondary source placement dependent on the error sensors positions and increases the workload of joint optimization. In this study, a method free from the information of specific error sensors positions is proposed. Using plane wave decomposition, the prior knowledge of primary pressures and acoustic transfer impedances is transformed to corresponding plane waves, and the cost function for active noise control is formulated in wave-domain. Simulated experiments are conducted to evaluate the proposed method and compare it with two other traditional methods. Results show that the proposed method can optimize the secondary source placement effectively, and better global noise reduction can be achieved.
