| Abstract: |
| Sound-absorbing foam glass was prepared from blast furnace slag. The effects of glass thickness, depth of cavity, side seam and opening porosity on absorption properties were investigated. The results show that increasing of thickness, depth of cavity, and opening porosity can improve sound absorption coefficient at low frequency, but the thickness exceeding 150 mm has little effect on absorption coefficient. Sound absorption coefficient rises with increasing of side seam only within the frequency range of 500~3 000 Hz. |
