Porous sound-absorbing materials are widely used because of its high sound absorption coefficient and wide absorption frequency range. In this paper, a model of sound absorption materials is adopted, and the design parameters are computed. The influence of porosity, diameter of holes, thickness and structure of the material on its sound-absorbing property is analyzed. This work provides a reference for the development of new sound-absorbing material.
