We propose a periodic structure that behaves as a fluid fluid composite for sound waves, where the building blocks are clusters of rigid scatterers. Such building-blocks are penetrable for acoustic waves, and their properties ...

[ES] Una de las soluciones para el control del ruido en su transmisión viene dada por la utilización de pantallas acústicas. Una pantalla acústica clásica consiste básicamente en un medio continuo de material rígido que ...

Absorption of broadband noise by sonic crystals consisting of microperforated cylindrical shells is proposed and experimentally demonstrated. The theoretical study has been performed in the framework of multiple scattering ...

The enhancement of sound inside a two dimensional exponentially chirped crystal during the soft reflections of waves is experimentally and theoretically explored in this work. The control of this enhancement is achieved ...

Uno de los objetivos en la Acústica de Salas consiste en la creación de un campo sonoro difuso. Los difusores de sonido pueden mejorar el rendimiento acústico de las salas, aumentando la difusión del campo sonoro, la ...

The properties of sonic crystals (SC) are theoretically investigated in this work by solving the inverse problem k(¿) using the extended plane wave expansion (EPWE). The solution of the resulting eigenvalue problem gives ...

We present the design of a structured material supporting complete absorption of sound with a broadband response and functional for any direction of incident radiation. The structure which is fabricated out of porous ...

[EN] Sonic crystal noise barriers (SCNB) have emerged as a promising solution for mitigating traffic noise pollution. These barriers utilize periodic structures to selectively reflect acoustic waves at specific target ...

[EN] Noise, and specifically noise generated by road infrastructure, is a major environmental pollution problem that causes many health problems for citizens in advanced societies. To reduce these environmental problems, ...
