Insulating Properties

We produced hierarchically porous materials using hydrogel templating and viscous trapping techniques and studied how their sound insulating properties depend on the pore size and porosity.

Flexible Models

In the paper basic theoretical models of transmission loss calculation are described. Here only single homogeneous isotropic panels are analysed. Three impedance values of one rigid and two flexible body models of panel are described and analysed. As flexible models the thin plate (Kirchhoff-Love plate model) i thick (Mindlin – Reissner model) are analysed.
