Acoustic wave diffraction at the upper edge of a two-dimensional periodic array of finite rigid cylinders. A comprehensive design model of periodicity-based devices

Castiñeira Ibáñez, Sergio; Rubio Michavila, Constanza; Sánchez Pérez, Juan Vicente (European Physical Society, 2013)

[EN] Diffraction at the upper edge of a two-dimensional periodic array of finite rigid cylinders immersed in air as well as the effect on its wave propagation properties are numerically and experimentally reported in this ...
An equivalent lattice-modified model of interfering Bragg bandgaps and Locally Resonant Stop Bands for phononic crystal made from Locally Resonant elements

Redondo, Javier; Godinho, Luis; Staliunas, Kestutis; Sánchez Pérez, Juan Vicente (Elsevier, 2023-08-31)

[EN] waves is a hot topic. An important class of these metamaterials is based on phononic crystals with Locally Resonant Structure, included in those commonly known as Locally Resonant Sonic Materials. In these metamaterials, ...
Comparative study of simulation methods for the quantification of the acoustic insulation provided by periodic structures

Parrilla-Navarro, Manuel Jesús; Redondo, Javier; Sánchez Pérez, Juan Vicente; Peiró-Torres, María Del Pilar (SOCIEDAD ESPAÑOLA DE ACUSTICA, 2018)

[EN] Nowadays there are different available methods to perform simulations in acoustics. The suitability of them strongly depends on the system studied in each case. In the present work, a comparison between different ...
Estudio del aumento de la difusión del sonido producida por cristales de sonido

Quintana Gallardo, Alberto (Universitat Politècnica de València, 2015-11-02)

El presente trabajo trata el estudio de la difusión y los parámetros acústicos, en una pequeña sala usando la técnica de simulación de Diferencias Finitas en el Dominio Temporal. El estudio se realiza en 3 condiciones ...
Reflection of sound by Sonic Crystals: an application to the aerospace engineering

García-Raffi, L. M.; Salmerón-Contreras, L. J.; Herrero-Durá, Iván; Picó Vila, Rubén; Redondo, Javier; Sánchez Morcillo, Víctor José; Cebrecos, Alejandro; Jimenez, Noe; Romero García, Vicente; Staliunas, K. (Universidade do Porto, 2016-06-15)

[EN] From the acoustical point of view one of the most extreme events is the lift-off of a rocket. In such events, an enormous amount of energy is liberated in the form of acoustic waves that are reflected in the launch ...
Sonic Crystals Acoustic Screens and Diffusers

Peiró-Torres, María Del Pilar; Parrilla-Navarro, Manuel Jesús; Ferri García, Marcelino; Bravo, Jose Maria; Sánchez Pérez, Juan Vicente; Redondo, Javier (Elsevier, 2019-05)

[EN] This article presents the use of advanced tools applied to the design of devices that can solve specific acoustic problems, improving the already existing devices based on classic technologies. Specifically, we have ...
