      Article
      Accés obert
      Uno de los parámetros más significativos de los altavoces es, probablemente, su rendimiento. Este puede definirse como la relación entre la potencia radiada y la potencia eléctrica consumida. Normalmente se expresa en % ...

    • Error estimation in vibroacoustic problems solved by means of finite elements 

      Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2010-06)
      Text en actes de congrés
      Accés obert
      The vibroacoustic equations can be solved by means of the finite element method. A discretisation of the structure and the acoustic domains is required and highly influences the quality of the numerical solution. There ...

    • Experimental investigation of loudspeaker power requirements 

      Sanz Ausín, Daniel (Universitat Politècnica de Catalunya / Denmarks Tekniske Universitet, 2014)
      Treball Final de Grau
      Accés obert
      Realitzat a/amb:   Danmarks tekniske universitet
      The components of a sound system, whether it is a small system for an electronic device or a high power one, need to be designed to meet certain power requirements. For this, manufacturers often design these components ...

    • Formation of high-order acoustic Bessel beams by spiral diffraction gratings
