A light transmitting panel composed of at least two panes held in spaced relation by a spacer assembly to define at least one space between panes is given improved sound damping properties by employing panes which exhibit at least two different masses per unit surface area, by causing the space between panes to be sealed from the external atmosphere, and by filling this space with a gaseous medium whose composition is such that the velocity of sound propagation therethrough is different from that in dry air at the same pressure and temperature as the med...
In a light transmitting panel composed of at least two panes and spacer means holding the panes in spaced relation to define an inter-pane space between adjacent panes, the improvement wherein, for imparting improved sound damping properties to said panel, at least two said panes have respectively different masses per unit light transmitting surface area, said inter-pane space is sealed from the atmosphere, and said panel comprises a gaseous medium filling said space and having a composition such that the velocity of sound propagation in said gaseous med...
