    • Panels for use in building construction (partitions, walls, ceilings, floors or doors) which exhibit improved acoustical sound proofing in multiple specific frequency ranges and also present improved structural integrity, are provided. The improved performance is achieved through the use of one or more layers of glue such that at least one layer of glue includes a viscoelastic material in a first pattern and a structural adhesive in a second, non-overlapping pattern. The viscoelastic material may have a varied shear moduli and functions as a glue and energy dissipating layer. In some embodiments, one or more constraining layers separating one layer of glue may be included. The constraining layer may be formed of a material such as gypsum, cement, metal, cellulose, wood, or petroleum-based products such as vinyl, plastic, or rubber. In some embodiments, standard wallboard, typically gypsum, comprises the external surfaces of the laminated panel.
    • 提供了在多个特定频率范围内表现出改善的声学隔音的建筑结构(隔板,墙壁,天花板,地板或门)中使用的面板,并且还提供了改进的结构完整性。 通过使用一层或多层胶水来实现改进的性能,使得至少一层胶水包括第一图案中的粘弹性材料和第二非重叠图案中的结构粘合剂。 粘弹性材料可以具有变化的剪切模量并且用作胶和消散层。 在一些实施例中,可以包括分离一层胶水的一个或多个约束层。 约束层可以由诸如石膏,水泥,金属,纤维素,木材或石油基产品如乙烯基,塑料或橡胶的材料形成。 在一些实施例中,标准墙板(通常为石膏)包括层压板的外表面。
