A finite element model of perforated panel absorbers including viscothermal effects

Carbajo San Martín, Jesús; Ramis Soriano, Jaime; Godinho, Luis; Amado-Mendes, Paulo; Alba Fernández, Jesús (Elsevier, 2015-04-01)

Most of the analytical models devoted to determine the acoustic properties of a rigid perforated panel consider the acoustic impedance of a single hole and then use the porosity to determine the impedance for the whole ...
A Simple Method to Estimate the In Situ Performance of Noise Barriers

Redondo, Javier; Gaja-Silvestre, Pau; Godinho, Luis; Amado-Mendes, Paulo (MDPI AG, 2022-07)

[EN] Noise barriers are usually classified attending to their intrinsic acoustic characteristics. This is standardized by the European Standards EN 1793, parts 2 and 6, in which a single parameter, DLR or DLSI, is defined ...
Normal incidence sound insulation provided by Sonic Crystal Acoustic Screens made from rigid scatterers - assessment of different simulation methods

Peiró-Torres, M.P.; Ferri García, Marcelino; Godinho, Luis M.; Amado-Mendes, Paulo; Vea-Folch, Francisco Jose; Redondo, Javier (EDP Sciences, 2021-07-20)

[EN] Sonic crystal acoustic screens have been in progressive research and development in the last two decades as a technical solution for mitigating traffic noise. Their behaviour is quite different from that observed in ...
