Planar acoustic metamaterials with the active control of acoustic impedance

Popis výsledku v původním jazyce

Předneseno:2013 International Workshop on Acoustic Transduction Materials and Devices, PennState, 07.05.-09.05.2013. Noise and vibrations affect our lives and the intensity of generated noise and vibrations has become an important parameter indicating the quality of environment. It is our everyday experience that one of the major noise sources in our homes and offices are windows and glazed facades. It is known that noise and vibrations are accompanied with the flow of acoustic energy and that propagation of acoustic energy in an acoustic medium and the reflection of noise at interfaces of two different media is controlled by a physical property called the acoustic impedance Z. It can be easily shown that by tuning the acoustic impedance of the planarstructure at the interface of acoustic media, one can achieve devices such as perfectly absorbing surfaces or perfect sound shields. It is clear that realization of two aforementioned devices usually requires such values of the
