Acoustic insertion loss due to two dimensional periodic arrays ofcircular cylinders parallel to a nearby surface

Krynkin, Anton; Umnova, Olga; Sánchez Pérez, Juan Vicente; Chong, Alvin Yung Boon; Taherzadeh, Shahram; Attenborough, Keith (Acoustical Society of America, 2011)

The acoustical performances of regular arrays of cylindrical elements, with their axes aligned and parallel to a ground plane, have been investigated through predictions and laboratory experiments. Semi-analytical predictions ...
Analytical model to predict the effect of a finite impedance surface on the propagation properties of 2D Sonic Crystals

Romero García, Vicente; Sánchez Pérez, Juan Vicente; García Raffi, Luis Miguel (IOP Publishing: Hybrid Open Access, 2011)

The use of sonic crystals (SCs) as environmental noise barriers has certain advantages from both the acoustical and the constructive points of view with regard to conventional ones. However, the interaction between the SCs ...
