Sound absorption materials are generally classified into three types, porous, resonator, and panel. All of these three types are based on the theory of energy transforming from sound energy to thermal energy. In this paper, we examined the sound absorption coefficient of recycled polyester nonwovens for the purpose of substituting the conventionally used materials such as glasswool and rockwool. The use of recycled polyester nonwovens has many advantages compared to conventional sound absorbers…
