This invention provides a system for integrating sound radiation from mid-range and high frequency sources enabling improved control over the radiation of high frequency sound waves. This acts to minimize the distortion, while enabling compression-loading of the mid-range sound waves increasing acoustic energy. To do so, a radiation boundary integrator ("RBI") having slots is positioned over the mid-range sound sources acting as a smooth sidewall wave-guide thus controlling the high frequency sound waves emanating from the high frequency sound sources. To allow the mid-range frequency sound waves generated from mid-range sound sources to pass through the RBI, slots are formed within the RBI. As such, RBI may have an outer surface area that may form an acoustical barrier to high frequencies radiating across the outer surface, yet be acoustically transparent to mid-range frequencies radiating through slots in the radiation boundary layer. The RBI may also serve as a volume displacement device to compression-load the mid-range sound sources. To do so, the back surface of the RBI may be contoured to the shape of the mid-range sound source thus reducing the space between the two, and loading the mid-range sound sources generating greater mid-range sound energy. |
