ANNEX C (informative) - Example computation of the insertion
loss of an outdoor noise barrier
Includes insertion loss determination, by measurement or by the combination of measurement and prediction, for outdoor noise barriers of all types and gives two methods for indirectly determining the level of the BEFORE sound. The two methods are: (1) by measurement at a second site that is equivalent to the desired site prior to installation of the barrier, or (2) by prediction of the BEFORE sound levels.
