Sažetak
The present invention discloses a resonator absorber with adjustable acoustic characteristics made in the form of a cuboid with the sidewalls (11, 12, 13, 14) and with the open upper face that is covered by two identical movable perforated plates (30, 40) to allow partial overlapping of the said plates. Each plate is equipped with bores forming a planar binary amplitude diffusor by using a maximum length pseudorandom binary sequence mapped to 2D space to determine the bore position. Bores are arranged in rows which do not overlap between plates. The resonator absorber has 6 cavities of different geometry situated below the perforated plates (30, 40), where 5 cavities simultaneously change the volume with movement of the perforated plates (30, 40). Resonator absorber is useful for tuning the acoustic characteristics of environment.
