机译:多通道主动防声墙及其主动降噪控制方法

摘要

PURPOSE: A multi-channel active soundproof wall and an ANC method thereof is provided to improve soundproof performance by applying a multi channel ANC method to a Y-shaped upper structure having high soundproof function. CONSTITUTION: A multi-channel active soundproof wall comprises a soundproof wall body(100), a soundproof wall upper end portion(200), and an ANC unit. The soundproof wall upper end portion comprises inner and outer soundproofing portions(210, 220) and is formed into Y-shape. One or more noise measurement units(10), one or more speakers, and one or more error measurement units are installed in the soundproof wall upper end portion. The ANC unit controls multi-channel based on one or more elements of the noise measurement units and the error measurement units.
