Provided in the present invention are an apparatus for controlling the remote shielding of an active-type sound outdoor, and a method thereof. The apparatus measures error noise including the surrounding noise with respect to a directional speaker in an outdoor space, analyzes noise shielding, generates an antiphase sound with respect to the sound outputted from a stage speaker, and outputs the same. Therefore, the apparatus is capable of forming a virtual soundproof wall by shielding and preventing the sound generated in an outdoor performance or the like from being spread outside except for a performance place. The apparatus for controlling the remote shielding of an active-type sound outdoor is equipped with a remote shielding control server (200) for remotely controlling stage sound equipment (100) and shielding sound equipment (300) through a web. |
