Noise Cancelation

This research has developed the active noise cancelation (ANC) equipment for reducing road traffic noise. This ANC equipment is consisted of microphones, controllers and speakers. This research has conducted simulation by using the noise source that was recorded at the roads to confirm the ANC equipment. The simulation conducted in the field used 1 non-directional speaker and 2-directional speakers. Also, this simulation applied the Fx LMS algorithm. The result of this study showed that the non-directional speaker was shown to reduce the maximum of 5.5 dB (A) in low frequency band. And, the 2 directional speakers was shown to reduce the noise for 2.5 dB (A) and 3.8 dB (A), respectively. This equipment did not diffuse anyexternal influence and operated stably.
