AB  - The use of porous materials in sound is quite well-known. The materials can be used for absorption of unwanted radiation, for dissipation, and re-distribution of the waves while travelling through the thickness of material and for enhancement of the overall sound and therefore energy transfer within the material. A three layer system comprising of two rigid layers of material with a soft gel middle layer between them was investigated in this research work to establish the effect of the gel material on the system’s energy performance. The role of the gel layer in transferring the energy to the panel was investigated. It was demonstrated by experiments that the gel layer between the top layer and the last layer enhances the performance of the overall construction and also minimizes the mechanical distortion by absorbing its bending waves. This effect enables to extend the radiating frequency of the construction up to high and down to lower frequencies.
