Textile materials used without any other structures show low absorption throughout the operating frequency range, and they are currently used for interior decoration. These fabrics can play an important role in the development of acoustic materials c

In an experimental investigation, the development of sonic crystal noise barriers (SCNBs) is undertaken to address the issue of train brake noise (TBN), focusing on the use of local resonances in scatterers of sonic crystals. Recent research has show

Helmholtz resonators (HRs) have the advantage of extending and improving their insulating capacity when used as scatterers in noise barriers made of periodic media, such as sonic crystals (SCs). However, the interaction between multiple Bragg scatter

The timple is a small traditional cordophone originary from the Canarian archipelago (one of the outermost regions of the Kingdom of Spain). Because of its morphology, it is similar tothe ukulele or the guitarro, but differs with them in that the bac

We report a theoretical and experimental study of an array of Helmholtz resonators optimized to achieve both efficient sound absorption and diffusion. The analysis starts with a simplified 1D model where the plane wave approximation is used to design

In this paper, a mathematical model describing the dynamic behavior of a commercial piezoelectric ceramic, vibrating in thickness, is presented. This model solves, by finite differences, the piezoelectric equations which relate he mechanical and elec
