    Abstract

    © 2015 by ASME. This paper investigates the effects of reflection surfaces on the performance of feedback active noise control systems. By using the classical control theory, the noise reduction level of a feedback active noise control (ANC) system with and without a single rigid reflecting surface has been derived. Numerical simulations have been carried out, and it is found that the smaller the distance between the microphone and secondary loudspeaker is, the more the noise reduction level will be achieved despite the rigid reflecting surfaces exist or not. Furthermore, numerical comparisons between the performance of the active feedback noise control system with and without rigid reflecting surfaces show that the presence of the rigid reflecting is beneficial for feedback active control.
