Abstract :
In this paper we show that the location of the secondary source is very important for acoustic ANC systems. We calculate sound propagation in a simulated room with complete reflection of sound waves from the walls by FDTD method. Then, we choose criteria for noise pressure level and find the best node for anti-noise source, and after that, we estimate optimal amplitude and phase for anti-noise signal that increase efficiency of the ANC system
