Claim Text:
1. A dynamic acoustic panel device, comprising: an enclosure having a base and a single front opening having a peripheral edge; an absorbent panel of sound absorbent material mounted on the base of the enclosure and having a front face spaced inward from the front opening; a multi-panel array mounted in the front opening in front of the absorbent panel at a predetermined spacing from the front face of the absorbent panel; the multi-panel array comprising an array of reflective panels arranged in a series of spaced rows, each row having a central axis extending across the front opening between opposing portions of the peripheral edge of the front opening, the panels in each row being rotatably mounted for rotation about the central axis of the respective row whereby the angle of inclination of each reflective panel in the row is adjustable from zero degrees to ninety degrees relative to the absorbent panel, the multi-panel array forming a substantially flat reflective surface at least substantially covering the absorbent panel in a zero degree position, and each panel in the multiple panel array extending substantially perpendicular to the absorbent panel in a ninety degree position in which the absorbent panel is exposed between adjacent rows of perpendicular panels, whereby the reflection and absorption characteristics of the panel device can be dynamically adjusted by varying the angle of panels in the array to any selected angle from maximum reflection at the zero degree position to maximum absorption at the ninety degree position.
