Title: Comparative analysis of the acoustic efficiency of classical and sonic crystal noise barriers
Keywords: acoustic efficiency, sonic crystals, noise barriers

Abstract: This study presents a comparative analysis of the acoustic efficiency of classical and sonic crystal noise barriers conducted by means of numerical simulation. One of the most commonsolutions for transport noise reduction isthe use of expensive combined noise barriers of high degree of reflection and absorption. Sonic Crystals are a relatively new type of noise barrier under development and investigation. In this study both types ofbarriers are compared on the basis of their area of application, noise level attenuation behind them, frequency response, technology of manufacturing, maintenance and price. Some of the characteristics are obtained throughnumerical simulations and experimental data, while othersare available inpublished research studies. On the basis of theresults conclusions about the application of sonic crystalnoise barriers are made.
