Web1 dec. 2014 · The insertion loss of the sound enclosure is given by (19) I L = 10 log W 0 W t r a n s = 10 log α + τ + δ τ + β. So far, we have assumed that the transfer of the acoustic power among elements occurs through one big panel whose area is equal to the interior surface area of the enclosure. WebHard ground reflects sound waves. Examples include roads and paved areas. For "Soft Ground" G = 1. Soft ground is porous and absorbs sound waves. Examples include grass, trees and other vegetation. For "Mixed Ground" use a value for G between 0 and 1 that represents the fraction of the ground that is soft. Barrier insertion cancels ground effects.
