The invention relates to a multiple window glass comprising a first laminated glass plate and a second simple or laminated glass plate, parallel to the first and separated from it by a gas layer, the two plates being held together in a gastight manner. The resin of the laminated glass of the first plate (1) is chosen so that a bar 9 cm long and 3 cm wide, consisting of a laminated glass comprising two glass sheets 4 mm thick joined by a 2 mm layer of this resin, has a critical frequency that differs at most 35% from that of a glass bar having the same length, same width and 4 mm thickness.

Multiple window glass comprising a first laminated glass plate and a second simple or laminated glass plate, parallel to the first plate and separated from it by a gas layer, the two plates being held together in a gastight manner wherein said first laminated glass plate comprises two simple glass sheets with a thickness between about 3 and 8 mm, joined by a layer of resin with a thickness at most equal to 10 mm and wherein the gas layer has a thickness between 6 and 30 mm and wherein the second plate has a thickness greater than 8 mm in the case of a simple glass, or is of a laminated glass meeting the same thickness criteria as the laminated glass of the first plate, and wherein the resin of the laminated glass of the first plate is chosen so that a bar 9 cm long and 3 cm wide, consisting of a laminated glass comprising two glass sheets 4 mm thick joined by a 2 mm layer of this resin, has a critical frequency that differs at most 35% from that of a bar of glass having the same length, the same width and 4 mm thickness. Acoustical window glass comprising at least a laminated window glass, wherein the resin of the laminated window glass is such that a bar 9 cm long and 3 cm wide, consisting of a laminated glass comprising two glass sheets 4 mm thick joined by a 2 mm layer of this resin, has a critical frequency that differs at most about 35% from that of a bar of glass having the same length, the same width and 4 mm thickness.
