Acoustical Characterization of Porous Materials for Automotive Application

There exists diversity when it comes to porous materials either artificial or natural. Sintered, steel wool, perforated materials and fiber metal are among the porous materials that have been increasingly used in automotive noise control. Following the diversity and variety of porous material characteristics, the study of porous media has proved to be wide and interesting. The review begins with outlining and comparing the models that are intended to be used in predicting the fundamental acoustical characteristics that are applicable in automotive. The paper introduces both the theoretical, empirical and numerical modeling and demonstrates how the models are used to determine the acoustic characteristics of porous materials. The analytical models indicate that the solid constituents of porous material are rigid and the fluid constituents are similar to that of a homogenous isotropic fluid that has been modified. The review also considers the acoustical characterization of porous materials and goes further to look at the porous materials modeling while having particular interests on porous materials that are elastic. The fundamental characteristics of porous materials are then illustrated using computational and experimental examples . Introduction In automotive, absorptive materials have various applications in different locations. ...Show more

Summary

Characterization models of poroelastic materials: A review
Several models have thus been proposed to easily predict the acoustical behaviour of poroelastic materials. These models often use various physical parameters that are based on definitions from theory or measurements from experiments (Seppi 2009). However, the accurate prediction or characterization of poroelastics is still a difficult issue, especially in the case of numerical simulations of materials having complex geometries, due to limitations of convergence and time taken for computation (Seppi).
