A sound adsorption ceramic and the production method thereof are provided. The sound adsorption ceramic is a ceramic with multiple intercommunicating pores, which comprises glass phase, quartz phase and mullite phase. The raw materials of the ceramic comprise 15-55wt% of ceramic waste residue, 15-25wt% of clay, 1.0-3wt% of talc, 0.01-10wt% of quartz, 10-45wt% of feldspar and proper amount of reinforcing agent, dispergator and water. 3-20wt% of Portland cement powder or 3-20wt% of Portland cement powder and at least one decomposable inorganic salt based on total weight of the raw materials is also added. Said raw materials are sintered at high temperature to obtain the ceramic. The sound adsorption ceramic has advantages of high sound adsorption coefficient, healthfulness, environment friendliness, fire prevention, long service life, moisture resistance, water resistance, moth resistance, static electricity resistance and ultraviolet ray resistance. The production method is low cost, simple ...
