摘要： A porous composite sound-absorbing material and a method for preparing the same are provided. The porous composite sound-absorbing material includes activated carbon cotton felt, zeolite particles, and an adhesive. The activated carbon cotton felt can bond the zeolite particles to fiber surfaces thereof by means of the adhesive, so that the zeolite particles are evenly dispersed and fixed and achieve optimal sound absorption performance. Meanwhile, a large number of micro-pore structures on surfaces thereof can act synergistically with the zeolite particles, so that the porous composite sound-absorbing material has significantly better sound absorption performance than the two and has extremely high cost performance. During the preparation process, the activated carbon cotton felt after treatments, is successfully compounded with the zeolite particles with more excellent sound absorption performance, so that the sound absorption performance is significantly improved and the cost performance is extremely high.

摘要： Panel systems and related methods of controlling sound transmission are discussed. For example, the panel system may include a sound control component, which may include a foam composite of a polymer and an inorganic filler. The panel system may further include an attachment mechanism, e.g., including at least one fastener, at least one bracket, and/or at least one rail or rail system. The attachment mechanism may be configured to secure the sound control component between a first wall and a second wall, such that the panel system controls sound transmission between the first and second walls.

摘要： Disclosed are a method for preparing a sound-absorbing member and a sound-absorbing member. The method for preparing a sound-absorbing member includes: providing non-foaming sound-absorbing material powder and a foaming material; uniformly mixing the non-foaming sound-absorbing material powder with the foaming material and adding an auxiliary to form a sound-absorbing mixture; and foaming the sound-absorbing mixture to form foam with cells, wherein the non-foaming sound-absorbing material powder adheres to a surface and the cells of the foam. The foamed sound-absorbing material powder and the foam constitute a sound-absorbing member.

摘要： The invention discloses a method for preparing mesoporous sound-absorbing material particles and mesoporous sound-absorbing material particles. The preparation method comprises the following steps. In step 1, sound-absorbing material powder and a templating agent are mixed with a binding agent and water to form sol slurry, the templating agent is an organic monomer or a linear polymer, and the templating agent has a purity greater than 95%. In step 2, the sol slurry is dropped into forming oil, and the droplets of the sol slurry are aged in the forming oil to form gel particles. In step 3, the gel particles are taken out from the forming oil and the gel particles are dried to form mesoporous sound-absorbing material particles. In step 4, the mesoporous sound-absorbing material particles are roasted.
