In this stud, perlite based coatings which can be applied to increase sound absorption capability of noise barriers, and especially use of concrete noise barriers, which is one of the forthcoming methods for overcoming the effects of environmental noise in urban areas caused by highway traffic, is examined in terms of design, experimental evaluation of physical and acoustic performance and costs. In the following stages of the study, considering decrease in the noise level in urban areas and reduction in the number of people adversely affected by traffic noise as economical benefits and comparing these with noise barrier construction and operation costs, also with application of perlite based coating, were evaluated, under certain assumptions, to evaluate its economic feasibility during the 50 years assumed life span of a concrete noise barrier.
