    摘要： A sound insulator, including an assembly of connected particles, wherein the connected particles include particles adjacent to one another that are adhered to one another. The particles that are adhered to one another include particles of random shapes and random sizes and having respective diameters falling within a range from about a quarter of a millimeter to about four millimeters. The particles that are adhered to one another are adhered such that they form a sound suppression blanket.

    摘要： The improved sound absorbing material comprises an aluminum base expanded metal (or an aluminum base metal screen) which is laminated with an aluminum base metal foil (or a thin resin film), or additionally with an aluminum base metal fiber layer. The aluminum base metal foil (or thin resin film) has ruptures, which vibrate in the process of sound absorption to permit the sound absorbing material to exhibit excellent sound-absorbing characteristics over a broad frequency range. The improved sound absorbing material can be produced by a process which comprises the steps of preparing a laminate comprising the members described above and pressing the laminate so that the individual members are compressed together while forming ruptures in a regular pattern in the aluminum base metal foil (or thin resin film).

    摘要： Body noise or mechanical vibrations are damped by a sound or noise dampingovering that may be secured permanently or temperarily to the surfaces of a body to be damped in the manner of an adhesive tape. The tape or band type damping covering comprises two layers of platelet elements of highly elastic material interconnected with play, for example by hooks. The layers are so arranged that the platelet elements in one layer are staggered relative to the platelet elements in the other layer. An intermediate layer of a plastic type material is interposed between the two outer platelet layers. The plastic material converts shearing stresses and hence the vibrations into heat. The plastic material may be a gel which absorbs liquid.

    摘要翻译： 身体噪声或机械振动被声音或噪音阻尼覆盖物阻尼，声音或噪音阻尼覆盖物可以永久地或缓慢地固定在被阻尼的物体的表面上，以胶带的方式。 带或带式阻尼覆盖物包括两层高弹性材料的血小板元件，例如通过钩子与游戏相互连接。 这些层被布置成使得一层中的血小板元件相对于另一层中的血小板元件交错。 在两个外部血小板层之间插入塑料型材料的中间层。 塑料材料将剪切应力转化为热量。 塑料材料可以是吸收液体的凝胶。
