    Broadband sound absorption by lattices of microperforated cylindrical shells 
    García Chocano, Víctor Manuel; Cabrera García, Suitberto; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics, 2012-10-29)
    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 ...

    Design, Manufacture and Characterization of an Acoustic Barrier Made of Multi-Phenomena Cylindrical Scatterers Arranged in a Fractal-Based Geometry 
    Castiñeira Ibáñez, Sergio; Rubio Michavila, Constanza; Romero García, Vicente; Sánchez Pérez, Juan Vicente; García Raffi, Luis Miguel (De Gruyter, 2012)
    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 ...

    Quenching of acoustic bandgaps by flow noise 
    Elnady, Tamer; Elsabbagh, A.; Akl, W.; Mohamady, O.; García Chocano, Víctor Manuel; Torrent Martí, Daniel; Cervera Moreno, Francisco Salvador; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics (AIP), 2009-03-30)
    We report an experimental study of acoustic effects produced by wind impinging on noise barriers based on two-dimensional sonic crystals with square symmetry. We found that the attenuation strength of sonic-crystal bandgaps ...
