Title: Lowering the noise level in the transport flows through reduction of the traffic barrier reflected noise
Keywords: Traffic barrier, noise reduction

Abstract: Reflected noise from traffic barriers usually leads to increasing of the noise level excited by the automobiles and trains. This effect requires the design of transport noise barriers for effective noise reduction behind them as well as to produce small level of reflected noise in source direction. This will effect in better noise environment for many passengers especially in case of busy traffic in rush hours. People affected by this effect are usually far more than the affected ones behind the barrier. One of the existed solutions is the use of expensive combined noise barriers with high degree of absorption. In this study a new passive transport noise barrier is designed, tested and analysed for a good reduction level of the reflected noise. It is done by appropriate design of the barrier profile performing source and reflected acoustic waves interference in small volumes near the barriers. The barrier construction, made by repeated, equally profiled elements, allows even the exist
