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.
