Three-dimensional multiresonant lossy sonic crystal for broadband acoustic attenuation: Application to train noise reduction

Broadband acoustic attenuation produced by a three dimensional (3D) locally resonant sonic crystal (LRSC), exploiting both the multiple coupled resonances and the Bragg band gaps, is numerically and experimentally reported in this work. The LRSC is made of square cross-section scatterers arranged on...
