A tunable acoustic barrier based on periodic arrays of subwavelength slits

Rubio Michavila, Constanza; Uris Martínez, Antonio; Candelas Valiente, Pilar; Belmar Ibáñez, Francisco; Gómez Lozano, Vicente (American Institute of Physics, 2015)

[EN] The most usual method to reduce undesirable enviromental noise levels during its transmission is the use of acoustic barriers. A novel type of acoustic barrier based on sound transmission through subwavelength slits ...
Análisis de la interacción de resonadores de Helmoltz en metamateriales acústicos periódicos en función de la orientación de incidencia de la fuente sonora

Ramírez Solana, David (Universitat Politècnica de València, 2020-09-15)

[ES] Las barreras acústicas basadas en cristales de sonido constituyen una de las apuestas tecnológicas más prometedoras de los últimos años en el campo de la acústica ambiental. Los cristales de sonidos se pueden definir ...
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 ...
Environmental noise control during its transmission phase to protect buildings. Design model for acoustic barriers based on arrays of isolated scatterers

Castiñeira Ibáñez, Sergio; Rubio Michavila, Constanza; Sánchez Pérez, Juan Vicente (Elsevier, 2015-11)

A new generation of acoustic barriers is being introduced into the noise control market. These barriers, based on arrays of isolated scatterers, present interesting properties to be used in cities to reduce the transmitted ...
Investigación del fenómeno acústico producido por redes de dispersores aislados y su aplicabilidad como dispositivos reductores de ruido en infraestructuras viarias

Peiró-Torres, M.P.; Sánchez Pérez, Juan Vicente; Redondo, Javier; Bravo, J.M.; Ferri García, Marcelino; Ballester-Ramos, M.; Vea-Folch, F.J. (ASOCIACIÓN ESPAÑOLA DE LA CARRETERA, 2021-06)

[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, ...
Numerical simulation and laboratory measurements on an open tunable acoustic barrier

Rubio Michavila, Constanza; Castiñeira Ibáñez, Sergio; Uris Martínez, Antonio; Belmar Ibáñez, Francisco; Candelas Valiente, Pilar (Elsevier, 2018)

[EN] A new open, thin and low frequency acoustic barrier is presented. These barriers, based on arrays of isolated pickets produce high acoustic attenuation in a selective range of frequencies related to their geometry and ...
Open noise barriers based on sonic crystals. Advances in noise control in transport infrastructures

Peiró-Torres, María Del Pilar; Redondo, Javier; Bravo Plana-Sala, José Mª; Sánchez Pérez, Juan Vicente (Elsevier, 2016)

Noise control is an environmental problem of first magnitude nowadays. In this work, we present a new concept of acoustic screen designed to control the specific noise generated by transport infrastructures, based on new ...
Optimum control of broadband noise by arrays of cylindrical units made of a recycled material

García Chocano, Víctor Manuel; Sánchez-Dehesa Moreno-Cid, José (Elsevier, 2013-01)

[EN] We report acoustic barriers that are designed to attenuate efficiently broadband noise. The barriers are structures consisting of only three layers of cylindrical units containing rubber crumb, a sound absorbing ...
Periodic systems as road traffic noise reducing devices: Prototype and standardization

Castiñeira Ibáñez, Sergio; Romero García, Vicente; Sánchez Pérez, Juan Vicente; García-Raffi, L. M. (Gheorghe Asachi Technical University of Iasi, 2015-12)

[EN] The design, the realization of the prototype and the acoustic standardization process of a novel periodic system made up of multiphysical phenomena scatterers as a road traffic noise reducing device are reported in ...
Sobre la medición del aislamiento de barreras acústicas basadas en cristales de sonido

Galiana Nieves, Jaime (Universitat Politècnica de València, 2020-10-15)

[ES] Las barreras acústicas suelen clasificarse atendiendo a sus características acústicas intrínsecas, fundamentalmente por el aislamiento que proporcionan. El método de medida está estandarizado en la norma europea EN ...
Subwavelength slit acoustic metamaterial barrier
