Numerical modelling of the radiation efficiency of asymmetrical structures
Poblet-Puig, Jordi; Rodríguez Ferran, Antonio; Guigou-Carter, Catherine; Villot, Michel (2009-05)
Article
Accés obertThe radiation efficiency of a structural element is required by some models in order to predict its sound insulation. A common assumption is that the radiation on both sides of the element is the same. This is not true for ... -

Sound transmission through double walls: statistical and deterministic models
Díaz Cereceda, Cristina; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2012)
Text en actes de congrés
Accés obertDouble walls are increasingly used in construction. Due to this, there is interest in reliable models of their sound insulation for the frequency range reguired in regulations (50-5000Hz). These models can be either ... -

Zárate, Roberto; Poblet-Puig, Jordi; Ortega, Martín; López-Parra, Marcelo (2020-06-18)
Article
Accés obertA Statistical Energy Analysis (SEA) model of a 510 liter capacity refrigerator is used to calculate the Sound Pressure Level (SPL) generated in a reverberation room. This is a reliable indicator of the vibroacoustic ... -
Sub-structuring of mechanical systems based on the path concept
Magrans Fontrodona, Francesc Xavier; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (Deutsche Gesellschaft für Akustik e.V. (DEGA), 2016)
Text en actes de congrés
Accés restringit per política de l'editorialReal mechanical systems are usually complex. Their modelling with discretisation techniques involve a large number of degrees of freedom/unknowns. This leads to high computational costs especially at high frequencies. An ... -
Suppression of spurious frequencies in scattering problems by means of boundary algebraic and combined field equations
Poblet-Puig, Jordi; Valyaev, Valery; Shanin, Andrey (2015-06)
Article
Accés restringit per política de l'editorialA numerical technique for solving scattering problems is presented. It is based on a boundary integral equation idea, so the unknowns are localized on the contour (in 2D case) or the surface (in 3D case) of the scattering ... -
