    • Numerical estimation of coupling loss factors in building acoustics 

      Díaz Cereceda, Cristina; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2013-10)
      Article
      Accés obert
      A study on the optimal procedure for obtaining SEA (statistical energy analysis) coupling loss factors (CLF) numerically is presented. The energies of an SEA system with two subsystems (one excited, the other one unexcited) ...

    • Numerical modelling of impact noise 

      Díaz Cereceda, Cristina (Universitat Politècnica de Catalunya, 2009-06-01)
      Tesina
      Accés obert
      El objetivo de esta investigación es desarrollar modelos determinísticos que permitan evaluar el aislamiento frente a ruido de impacto para diferentes tipos de forjados. Estos modelos abordan el problema mediante una ...

    • Pushing SEA beyond its limits: a model for real building structures 

      Díaz Cereceda, Cristina; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2013)
      Text en actes de congrés
      Accés obert
      The main challenge for models of building acoustics is being able to consider all the geometrical and physical details of real structures with a reasonable computational cost for high frequencies. The SEA (Statistical ...

    • 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 obert
      Double 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 ...

    • The finite layer method for modelling the sound transmission through double walls 

      Díaz Cereceda, Cristina; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2012-10)
      Article
      Accés obert
      The finite layer method (FLM) is presented as a discretisation technique for the computation of noise transmission through double walls. It combines a finite element method (FEM) discretisation in the direction perpendicular ...

    • Variant de la C-13 al pas per Tremp 

      Díaz Cereceda, Cristina (Universitat Politècnica de Catalunya, 2009-11-01)
      Projecte/Treball Final de Carrera
      Accés obert
      La carretera C-13 es una carretera de la Red Básica Primaria de Catalunya que une el Segrià con el Pallars Sobirà, atravesando las comarcas del Segrià, la Noguera, el Pallars Jussà y el Pallars Sobirà. Dada su ubicación, ...
