|Porous materials, which is widely used to control the noise, divided into fluid phase and solid phase. Accordingly, it can be characterized by acoustical parameters (flow resistivity, porosity, tortuosity, viscous characteristic length, and thermal characteristic length) due to the fluid phase and elastical parameters (Young’s modulus, loss factor, and Poisson’s ratio) due to the solid phase. These physical characteristics of the porous materials are essential to predict the acoustical properties such as wavenumber, surface impedance, absorption coefficient, and so on. Therefore, this study focuses on accurate measurement of several physical characteristics (porosity, tortuosity, elastical parameters) using the Porosity/Bulk density meter, Tortuosity meter and QMA developed by Mecanum Inc., respectively. We suggest setup values for measurement such as pressure, excitation frequency, etc. to reduce uncertainties of the results. Finally, the predicted and measured absorption coefficient are compared to verify the reliability of measured physical characteristics of porous materials. In addition, using global sensitivity analysis, the effect of the measurement deviation of the physical characteristics on the sound absorption coefficient is confirmed.
