    • An acoustical diffuser is disclosed for diffusing sound. A preferred diffuser includes a first fibrous material, a first separator layer, a diffuser material a second separator layer, a second fibrous material and an acoustically transparent material. The subject invention also includes a preferred method of molding such diffuser. The subject invention further includes a panel that has an acoustically reflective side and an acoustically transparent side over a frequency range that can be attached to the walls of a room to enhance the acoustical characteristics of the room. A preferred method of installing such panels includes installing fabric retainer members to the walls between the panels and attaching an acoustically transparent material to the fabric retainer members such that the panels and fabric retainers are covered by the acoustically transparent material. The panels may preferably be arranged such that acoustically reflective surfaces on one wall oppose acoustically absorptive surfaces on another opposing wall. Preferably, panels are attached to the walls such that the acoustically absorptive surfaces thereof are facing the room interior where the walls abut each other to form corners. An acoustical built-in wall system and an acoustical door and method of applying an acoustical treatment to a door are also disclosed.
    • 公开了用于扩散声音的声扩散器。 优选的扩散器包括第一纤维材料,第一隔离层,扩散材料,第二隔离层,第二纤维材料和声透明材料。 本发明还包括模制这种扩散器的优选方法。 本发明还包括一个在频率范围内具有声学反射侧和声学透明侧的面板,该面可附接到房间的墙壁以增强房间的声学特性。 安装这种面板的优选方法包括将织物保持构件安装到面板之间的壁上并将声透明材料附接到织物保持构件上,使得面板和织物保持器被声透明材料覆盖。 优选地,这些面板被布置成使得一个壁上的声反射表面与另一个相对的壁上的吸声表面相对。 优选地,板被附接到壁上,使得其吸声表面面向房间内部,其中壁彼此邻接以形成拐角。 还公开了一种声学内置的墙壁系统和声门以及对门进行声学处理的方法。
