DYNAMICALLY ADJUSTABLE ACOUSTIC PANEL DEVICE, SYSTEM AND METHOD

摘要

A dynamic passive acoustic panel device comprises an enclosure having a front opening, an absorbent panel of sound absorbent material mounted in the enclosure behind the front opening, and a reflective surface mounted in the front opening in front of the absorbent panel. The reflective surface comprises a tessellated array of reflective panels of matching shape arranged in a series of rows, each row being mounted for rotation about a central axis so as to vary the angle of inclination of the reflective panels in each row relative to the absorbent panel from zero degrees to ninety degrees to the absorbent panel, so as to vary the reflection and absorption characteristics of the panel device. A control system controls rotation of the rows of reflective panels, so as to vary the reflection and absorption levels between maximum reflection and maximum absorption based on desired acoustic properties of a space in which the panel device is located.

主权项

1. A dynamic acoustic panel device, comprising:
an enclosure having a base and a 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.
