| Abstract: | The widely used high sound absorbing material at present usually consists of fiberglass, mineral and rockwool and so on. These absorbers are complex structures and difficult to construct. This paper suggests a combined absorber in which expanded perlite is filled in honeycomb. It has some advantages of high sound absorbing coefficient, high rigidity, fire-resistance, withstand impact and convenient to construct. The influence factors of absorbing property have been studied in this paper. Such new absorbers have been applied in some practical work, and good results are obtained. |
