Abstract
In analogy with the structures discovered by Suzuki in alkali halides, in this article we introduce a twodimensional acoustic system consisting of a periodic distribution of impurities ~vacancies! in a host array. A triangular lattice of cylindrical sound scatterers is chosen as the host. The sonic crystal, called the Suzuki phase, shows extraordinary sound transmission properties: it holds the attenuation bands of the host structure and it also presents additional ones associated to the periodicity of the missing cylinders. The experiments agree with predictions based on the calculated acoustic band structure and they are explained by an analysis of eigenstates.
