    • PURPOSE: An acoustic panel system is provided to embody NRC(Noise Reduction Coefficient) performance by embodying a resonator structure and a porous sound absorber structure simultaneously. CONSTITUTION: An acoustic panel system(100) comprises: an inorganic board(110) having a resonator(115) structure to control the diameter of a hollow by frequency bands; a perforated sheet(120) arranged on one side of the inorganic board and provided with plural minute perforations to control the diameter by frequency bands; and a porous sound absorbing material(130) arranged between the perforated sheet and the inorganic board to absorb the noise energy entered to the perforated sheet with resistance of the porous sound absorbing material.
    • 目的:通过同时体现谐振器结构和多孔吸声结构,提供声学面板系统来体现NRC(降噪系数)性能。 声学面板系统(100)包括:具有谐振器(115)结构的无机基板(110),用于通过频带来控制中空部分的直径; 布置在所述无机基板的一侧上并具有多个微小孔的多孔板(120),以通过频带来控制所述直径; 以及多孔吸声材料(130),其设置在所述多孔板和所述无机基板之间,以吸收通过所述多孔吸音材料的电阻进入所述多孔板的噪声能量。
