Transmission Loss

Because the materials modelled by Zorba are porous the transmission loss can not be modelled by the mass law and for typical materials the transmission loss is low for thickness less than about 100 mm. However for certain situations where you have large thicknesses of porous material you can achieve quite worthwhile transmission losses due to the propagation losses due to friction in the material. Zorba will calculate the TL through the material and displays the results on the Table page.
