Title (EN) SOUND AND VIBRATION CONTROL WINDOWS
(FR) FENETRES DE PROTECTION CONTRE LE BRUIT ET LES VIBRATIONS
Abstract:
(EN) A transparent vibration and sound control mechanism is disclosed. The control mechanism may include a piezoelectric material disposed between patterned electrodes. The control mechanism may be incorporated into a window so that sound waves incident on one side of the window are not reradiated on the opposite side of the window.
(FR) La présente invention concerne un mécanisme transparent de protection contre les vibrations et le bruit. Ce mécanisme de protection peut inclure un matériau piézo-électrique disposé entre des électrodes faites par gabarit. Ce mécanisme de protection peut être intégré à une fenêtre de façon que le ondes sonores arrivant en incidence sur une face de la fenêtre ne soient pas réémises par la face opposée de la fenêtre.
