GLAZING HAVING IMPROVED ACOUSTIC PERFORMANCE
The invention concerns a glazing (1) having improved acoustic performance, the glazing (1) comprising at least one transparent substrate (2) comprising, on at least one of its faces, a preferably periodic network of transparent piezoelectric transducers (3) and a plurality of resonant electrical circuits (8), each transparent piezoelectric transducer (3) being connected to a single resonant electrical circuit (8) such that the substrate forms a transparent metamaterial. The invention makes it possible to improve the acoustic insulation of a glazing over a frequency band in the audible range.
本发明涉及一种具有改善的声学性能的窗玻璃(1)，该窗玻璃(1)包括至少一个透明基材(2)，该透明基材在其至少一个面上包括优选地周期性的透明压电换能器阵列(3)和多个谐振电路(8)，每个透明压电换能器(3)与单个谐振电路(8)连接，以使该基材形成透明的超材料。本发明使得可以改善窗玻璃在可听域的频带中的隔音性。
