    • Aircraft localization using a passive acoustic method. Experimental test 

      Martín Román, Sara-Regina; Genesca Francitorra, Meritxell; Romeu Garbí, Jordi; Clot Razquin, Arnau (2016-01)
      Article
      Open Access
      A passive acoustic method for aircraft localization is experimentally tested in this paper. The method relies on the Doppler effect influencing the signals received by a mesh of microphones distributed over the acoustic ...
    • Broadband and Intense Sound Transmission Loss by a Coupled-Resonance Acoustic Metamaterial 

      Roca Cazorla, David; Hussein, Mahmoud (2021-11-01)
      Article
      Open Access
      The advent of acoustic metamaterials has opened up an emerging frontier in the control of sound transmission. A key limitation, however, is that an acoustic metamaterial based on a single local resonator in the unit cell ...
    • Realitat augmentada amb "head transfer response function" (HTRF) 

      Díaz Cívico, Eric (Universitat Politècnica de Catalunya, 2019-05-22)
      Bachelor thesis
      Restricted access - author's decision
      La "head transfer response function" (HTRF) és un funció que permet processar un so de manera que a un oient amb el dispositiu adient (habitualment uns auriculars) li sembli que el so provingui d'un punt en concret. En ...
    • Simulació, control i mesura del patró de directivitat d'un sistema array de fonts sonores 

      Castan Girona, Albert (Universitat Politècnica de Catalunya, 2016-06-09)
      Bachelor thesis
      Restricted access - author's decision
      Per incrementar la intel·ligibilitat d’un sistema de so, és convenient poder controlar la directivitat de les fonts sonores. Aquest control dóna com a resultat la projecció del so a àrees específiques, intentant al mateix ...
    • Study: numerical tools for computational aeroacoustics 

      Eiximeno Franch, Benet (Universitat Politècnica de Catalunya, 2020-06-30)
      Bachelor thesis
      Restricted access - author's decision
      Aeroacoustics is the study of the noise produced by an airflow. The present work is focused on implementing a suite of code including a parallel code in C and scripts in Matlab and Python that can, coupled with a CFD ...
    • Terminal digital para la transmisión de voz y datos sobre banda fónica 

      Rodríguez Fonollosa, José Adrián; Ymbern García, Marcelo; Masgrau Gómez, Enrique José (Consejo Superior de Investigaciones Científicas (CSIC), 1986)
      Conference report
      Open Access
      The development of a terminal for voice and data transmision based on the TMS 32010 one-chip microprocessor is described. Simple solutions are provided for the digital implementations of the filters, compandor, equalizer ...
