Abstract
In this paper, a new method of using advance beamforming algorithm is proposed to control target focused found. The advance beamforming algorithm that adjusts the timing of sound waves emitted from each speaker in an array. As a result, sound waves cancel each other out in some parts of space, and amplify each other in others, effectively creating a focused beam of sound that acts as target focused sound. Even as you walk around your office, the advance beamforming algorithm would allow speakers to work like virtual headphones.
