Environmental noise pollution and its impact on human beings remains to be an important topic in acoustics. Conservative estimations of the World Health Organization have shown that traffic related noise alone causes a loss of approximately one million healthy life years, only within Western Europe. Broad selections of noise control devices to attenuate road traffic noise during propagation are available. Still, traditional noise barriers are most commonly used, but alternative solutions exist. A solution with great potential is to place periodic arrangements of cylinders in between the source and the receiver, often referred to as sonic crystal (SC) noise barriers. Generally, there are two important frequency regimes when using a SC, i.e. ...
