Active Noise Control Using Acoustic Holography in Local Free Space
Luo Xiang · Audio Engineering · 2009
The technology of acoustic holography is researched, and an active noise control method using acoustic holography in local free space is proposed. Then intensity of secondary sources is computed based on the rebuild pressure at the mistake points. The method is discussed in theory to expresses the feasibility and the correctness. A simulation is made using monopoly sources. As a result, active noise control using acoustic holography method can control the noise ideally.
