Acoustic panel and mounting method thereof
The invention provides an acoustic panel and a mounting method thereof. The sound-absorbing plate comprises at least one sound-absorbing unit, and each sound-absorbing unit comprises a micro-perforated panel and a micro-perforated back plate which are oppositely arranged; the honeycomb structure is arranged between the micro-perforated panel and the micro-perforated back plate; wherein each of the micro-perforated panel and the micro-perforated back plate is provided with at least one micropore, and the aperture of the micropore is smaller than or equal to 1mm; in addition, the micro-perforated panel, the micro-perforated back plate and the honeycomb structure jointly define a plurality of resonant cavities, and each resonant cavity is communicated with at least one micropore. The acoustic panel can generate a plurality of absorption peaks with high sound absorption coefficients on a frequency spectrum, so that a better sound absorption effect can be realized in a wider frequency band range.
本申请提供一种吸音板及其安装方法。该吸音板包括至少一个吸音单元，吸音单元包括相对设置的微穿孔面板和微穿孔背板；以及设于微穿孔面板和微穿孔背板之间的蜂窝结构；其中，微穿孔面板和微穿孔背板均开设有至少一个微孔，微孔的孔径小于或等于1mm；并且，微穿孔面板、微穿孔背板、蜂窝结构共同围合形成多个谐振腔，每个谐振腔与至少一个微孔连通。上述吸音板可以在频谱上产生多个高吸声系数的吸收峰，从而能够在较宽的频带范围内实现较佳的吸声效果。
