| Abstract: | The foamed aluminum is a functional material with wide application. The mechanism,structure of acoustic absorption as well as the influences of porosity rate,compression rate,thickness of foamed aluminum and thickness of air layer on the acoustic absorption are briefly reviewed,and some examples of foamed aluminum application on noise control are offered. |
