Abstract
An acoustic ceiling tile system is provided with individual tiles contoured in three dimensions in order to disperse sound energy over the entire audible range human hearing while also absorbing energy from the short and medium wavelength portions of the audible range. In a preferred embodiment, the individual tiles each comprise a peripheral flat portion of size and shape for fitting into a standard suspended ceiling structural grid and an interior convex portion, preferably in the shape of sinusoidal curveloid, for dispersing sound.
Claims25
An acoustic tile ceiling system comprising:
- a suspended ceiling structural grid adapted to hold a plurality of individual acoustic tile elements;
- a pluraliity of smoothly contoured acoustic tile elements, each tile element having a surface thereof adapted to form a ceiling surface when installed within said ceiling structural grid;
- said tile element surface exhibiting a curvature substantially as a surface of revolution varying smoothly and without abrupt changes from a substantially horizontal aspect at the periphery of said tile element through an increasingly downwardly projecting curvature to an inflection point through a decreasingly downwardly projecting curvature to a central, substantially horizontal portion, depressed at least 5 centimeters below the peripheral portion;
- each said tile element forming in the composite with adjacent tile elements as installed in said structural grid, a substantially continous smoothly flowing curvature, particularly adapted to disperse long wave length audible sound.
An acoustic ceiling tile for placement in a suspended ceiling structural grid comprising:
- a contoured body of acoustic absorbing material having a maximum width and a normally downwardly facing surface;
- said normally downwardly facing surface exhibiting a curvature substantially as a surface of revolution varying smoothly and without abrupt changes from a substantially horizontal aspect at the periphery of the body through an increasingly downwardly projecting curvature to an inflection point through a decreasingly downwardly projecing curvature to a central, substantially horizontal portion, depressed at least 5 centimeters below the peripheral portion;
- said body adapted to form, in conjunction with adjacent bodies when installed in said structural grid, a substantially continuous, smoothly flowing surface curvature particularly adapted to disperse long wave length audible sound.
