Personal sound zone synthesis by multizone sound field control

In a general sound system, sounds spread in all directions; thus, interference of multiple sounds can be noisy, and sounds can be delivered to someone who does not want to hear. Local-field sound reproduction aims to synthesize personalized sound zones by multizone sound field control with multiple loudspeakers.
