The research focuses on the efficiency of sound barriers in protecting against traffic-induced noise, with a specific focus on the example of barrier construction along the "A" highway in Sarajevo. The study aims to analyze the results of measuring daily and nightly noise levels at five different locations along the route, using standard methods and tools for noise measurement. The methodology involved constructing walls made of steel supporting columns and transparent panels of varying heights, and conducting control measurements of daily and nightly noise levels. The research results indicate that sound barriers are effective in reducing noise in the vicinity of roadways, especially during the daytime. However, nighttime noise values were slightly higher than the maximum allowable values, indicating the need for additional measures to control noise during nighttime hours. The importance of proper planning, construction, and maintenance of sound barriers is emphasized to ensure a better living environment for urban residents and reduce irritation caused by traffic noise.
