| Abstract: | Dimension analysis is one of the important qualitative and semi-quantitative analysis methods to study physical problems. By analyzing the structure parameters of influence sound-ab- sorbing properties of metal foam, and using Rayleigh＇s analysis to study sound-absorbing per- formance of metal foam, we try to provide a new method which combines the measurement and caculation to predict the sound absorption performance of metal foam. |
