SOUNDPROOF DEVICE STRUCTURE FOR REDUCING BROADBAND NOISE

摘要

PURPOSE: A soundproof device structure for reducing broadband noise is provided to reduce various noises by a multiple diffraction effect and an interference effect. CONSTITUTION: The soundproof device structure for reducing broadband noise comprises the steps of: installing a floor(2) horizontally on a soundproofed wall(1); and erecting many wings(3) on the floor(2) at regular intervals to the longitudinal direction of the soundproofed wall(1).
