• Resumen

  • Nowadays there are different available methods to perform simulations in acoustics. The suitability of them strongly depends on the system studied in each case. In the present work, a comparison between different methods (Multiple Scattering, Finite Elements Method and Finite Difference Time Domain) is carried out particularized to the quantification of the isolation provided by periodic structures (Sonic crystals). It has been considered a systematic study about computational time, precision and computational cost.
