Active Noise Control Algorithm Development through 3-Dimensional sound

Abstract

Active noise control (ANC) method is noise reduction method by generate anti-phase control signal for destructive interference of through control speaker. Purpose of this study was to develop the Active Noise control algorithm using the WFS(Wave field Synthesis) that is one of the three-dimensional sound reproduction method. The simulation was performed to check the direction of control sound source in the listener’s position. As a result, when used WFS active noise control, it was confirmed that it is able to generate control plane wave in the same direction as the noise source at the listener position. Also we were confirmed that efficiency of WFS Active noise control though the Comparison experiments with existing active control method. Based on these Results, when used WFS active noise control, it is can be reduce noise in the listener’s both side ear.
