Title
(EN) MULTI-PANE GLAZING FOR IMPROVED SOUND ATTENUATION
(FR) VITRAGE À VITRES MULTIPLES POUR ATTÉNUATION SONORE AMÉLIORÉE
Abstract
(EN)
A process for making a multi-transparency glazing that has similar nominal weight as a standard two-transparency laminate glazing that has been determined to increase acoustic attenuation over coincidence frequencies of monolithic and two-transparency design using multistage damping to further convert vibrational energy to heat.
(FR)
L'invention concerne un procédé de fabrication d'un vitrage à transparence multiple qui a un poids nominal similaire à celui d'un vitrage feuilleté à deux transparences standard qui a été déterminé pour augmenter l'atténuation acoustique sur des fréquences de coïncidence de conception monolithique et à deux transparences utilisant un amortissement à étages multiples pour convertir davantage l'énergie vibratoire en chaleur.
