| Abstract: | A new type of acoustic screen was made by using foamed aluminium materials produced by Northeastern University. The rational structure of the new foamed aluminium acoustic screen was studied, and its sound insulation effect was tested. The results indicate that the new type of foamed aluminium acoustic screen is effective and could reduce ambient noise by 20～30 dB within low\|frequency range, which shows that it is an advanced sound insulation screen and has a bright application perspective. |
