“…The analytical and numerical models physics considered were verified experimentally. Results can be compared with measurements on a reduced scale model [31][32][33][34][35]. This can reduce the costs and gives results for controlled environments, but requires special care in the frequency conversion and material selection for the construction of the barrier and floor, and in the choice of sound source and receptor.…”

The use of acoustic barriers has become a common solution to control and reduce the nuisance caused by transportation noise (e.g. highways, railroads, and aircraft). Acoustic barriers can be defined as any solid obstacle that blocks the straight line between sound source and receptor creating an acoustic shadow region behind. The precise prediction of acoustic barrier behaviour has been the goal of researchers, but the complexity of the phenomenon prevents generality. Many theoretical models are available but they are limited to particular cases. The main objective of this work is to carry out comparisons between the results obtained for the insertion loss using analytical methods of prediction, numerical methods using the Finite Elements Method (FEM) and Boundary Elements Method (BEM) and experimental measurements in the laboratory.

“…Christopher W. Menge (1980) presented studies of the effectiveness of barriers sloped away from a highway. 2 Studies have suggested that noise barrier faces sloped away from a highway would eliminate or reduce the reverberant build up of sound energy that occurs between parallel barriers. Poor performance was obtained when the barriers were vertical (0 degrees).…”

Effectiveness of Noise Barriers Tilted towards the Traffic Way over Bridges

Traffic noise over bridges and its impacts can be substantially reduced with road side barriers. A single barrier erected on one side of a bridge way can often provide the most effective solution. A single barrier may not always be sufficient, particularly in urban settings. In these cases, barriers may be necessary on both sides of the bridge. This paper presents a study of the effectiveness of barriers tilted towards the traffic with different angles and shapes to reduce the effect of the reflected sound waves from the second barrier. The insertion loss was determined at many points distributed horizontally and vertically behind the barrier.
