| description | In this work we present the design and the manufacturing processes, as well as the acoustics standard-
ization tests, of an acoustic barrier formed by a set of multi-phenomena cylindrical scatterers. Periodic
arrangements of acoustic scatterers embedded in a fluid medium with different physical properties are
usually called Sonic Crystals. The multiple scattering of waves inside these structures leads to attenuation
bands related to the periodicity of the structure by means of Bragg scattering. In order to design the
acoustic barrier, two strategies have been used: First, the arrangement of scatterers is based on fractal
geometries to maximize the Bragg scattering; second, multi-phenomena scatterers with several noise con-
trol mechanisms, as resonances or absorption, are designed and used to construct the periodic array. The
acoustic barrier reported in this work provides a high technological solution in the field of noise control. |
