Correlation between objective and subjective assessment of noise barriers

Redondo, Javier; Peiró-Torres, M.P.; Llinares Millán, María Del Carmen; Bravo, Jose Maria; Pereira, A.; Amado-Mendes, P. (Elsevier, 2021-01-15)

[EN] There are several international standards that define the way to evaluate the attenuation capacity of noise reducing devices, by single-number quantities representing airborne sound insulation and insertion loss. These ...
Increasing the Insertion Loss of Sonic Crystal Noise Barriers with Helmholtz Resonators

Redondo, Javier; Ramírez-Solana, David; Picó Vila, Rubén (MDPI AG, 2023-03)

[EN] Helmholtz resonators (HRs) have the advantage of extending and improving their insulating capacity when used as scatterers in noise barriers made of periodic media, such as sonic crystals (SCs). However, the interaction ...
New devices for noise control and acoustic cloaking

García Chocano, Víctor Manuel (Editorial Universitat Politècnica de València, 2015-07-13)

[EN] The aim of this work is to design new acoustic devices based on arrangements of scattering units. First, the use of sonic crystals as noise barriers for traffic noise control is comprehensively analyzed. Due to the ...
Research of the acoustic phenomenon produced by isolated scatterers and its applicability as a noise reducing device in transport infrastructures. Search for an optimised and sustainable design.

Peiró Torres, María del Pilar (Universitat Politècnica de València, 2021-03-30)

[ES] El control de ruido ambiental es una preocupación de primera magnitud para las sociedades avanzadas, debido a los problemas derivados que ocasionan en la salud de los ciudadanos. Una de las soluciones más extendidas ...
Sonic Crystal Noise Barrier with Resonant Cavities for Train Brake Noise Mitigation

Ramírez-Solana, David; Galiana-Nieves, Jaime; Picó Vila, Rubén; Redondo, Javier; Sangiorgio, Valentino; Vito Graziano, Angelo; Parisi, Nicola (MDPI AG, 2024-04)

[EN] In an experimental investigation, the development of sonic crystal noise barriers (SCNBs) is undertaken to address the issue of train brake noise (TBN), focusing on the use of local resonances in scatterers of sonic ...
