摘要：Because of the population growth, high-rise building and heavy traffic, modernbig cities and towns suffer from the increasing noise pollution problem.Therefore, reduction of noise becomes an important and challenging task for thesustainable development of modern cities. Meanwhile, industrial product such asmachinery, home appliances and air moving devices need to be usedsignificantly quieter because of customer‟s requirement and competition amongmanufactures. As a result, noise problem becomes more and more important anda new noise abasement technology should be developed to achieve the requiredenvironment or to improve the product quality. Noise control is, however, not asimple task. To adopt effective and economic control solutions, engineers mustbe able to understand the principles of sound generation and transmission as wellas available noise control strategies. There are several ways to reduce noise, andthe Helmholtz resonators (HR) are one of the most used filters.The acousticwave propagation in periodic structures has attracted growing interest in recentdecades. Many periodic structures were studied and various theoreticalapproaches were used. All have highlighted the existence of physical propertiessuch as the presence of forbidden bands corresponding to high attenuation, andbandwidth corresponding to a negligible attenuation. In this work, we study aperiodic structure formed by Helmholtz resonators (HR). We use two methods ofanalysis: the Transfer Matrix Method (TMM) and the Function InterfaceResponse (FIR) or Green's Function Method (GFM). We note at the outset thatthese methods lead to the same results.
