Traffic noise control using sound barriers

Traffic noise is one of the main elements that contribute more and more to noise pollution of the environment due to the increasing growth of traffic intensity. As a result, the need has arisen to increase the level of protection from this noise for both the people and the environment in areas located in the vicinity of the most frequent routes such as highways and major city streets. Various methods of noise protection can be applied, e.g. the displacement of roads, which can be difficult to implement, or the construction of physical barriers. There are several types of physical barriers, such as sound barriers, embankments, green belts, etc. and the choice of the appropriate type is guided with factors like location, size, acoustic properties (absorption and reflection coefficient), resistance to external influences (waterproofness, stability at high speed winds, temperature changes, etc.), cost effectiveness, ease and speed of construction and also aesthetics. The main advantage of sound barriers is a high level of protection that can be achieved at a minimum cost in a short time through appropriate design and choice of materials required for construction. Various types of sound barriers are available and can be placed in different ways, depending on the fore mentioned factors. In this paper we will show different types of sound barriers and various ways of setting them for particular situations. The construction of a real sound barrier will be presented.
