This study analyzed the effect of two-way noise barriers on insertion loss for road traffic noise. For this purpose, a study was conducted on the reduction of insertion loss of two-way noise barriers using CadnaA (Ver. 4.3), a 3D environmental noise prediction program equipped with the road traffic noise prediction formula RLS-90. When installing a two-way noise barriers, the reduction in insertion loss according to the number of lanes, the height of the noise barrier, and the sound absorption rate was analyzed.
