Abstract
An acoustic panel (1), comprising: a rear wall (3), side walls (4) and a front wall (2) having a longitudinal and a transverse direction and comprising an area consisting of elongated cellular elements (7) connected by their longer sides in the transverse direction of the front wall (2), wherein each of the cellular elements (7) contain at least one mirror-like sound-reflecting surface (5) and at least one recess (6) changing the phase of a reflected acoustic wave, characterized in that the recess (6) changing the phase of the acoustic wave has a shape of a well (8) to which at least one acoustic resonator (9) is attached substantially perpendicularly, wherein at least two cellular elements (7) constitute a system having property of shaping dissymmetrically the directivity characteristic of the reflected acoustic wave.
