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.
