The invention relates to a sound absorption plate for a building, and discloses a color-sand sound absorption plate. The color-sand sound absorption plate (1) is an integrally formed plate composed ofat least two sub sound absorption plates (2) with different colors, wherein each sub sound absorption plate (2) is formed by bonding a binding agent with color-sand particles which have a color corresponding to the color of the sub sound absorption plate, the binding agent covers the outer surfaces of the color-sand particles, the color-sand particles are combined through the bonding agent, and gaps among the color-sand particles covered by the binding agent form sound absorption pores. The color-sand sound absorption plate provided by the invention has good sound absorption performance and excellent decoration performance; the decoration effect can be designed according to the situation, and can be freely transformed and combined; and in addition, the color-sand sound absorption plate also has the advantages of simple preparation process and low manufacturing cost.
