Paneelabsorbers

Paneelabsorbers are flat, rigid-faced acoustic treatment devices designed to attenuate sound by converting acoustic energy into heat through viscous losses in a backing cavity or porous material. They are mounted on walls or ceilings to reduce early reflections, improve speech intelligibility, and shape the tonal balance of a room. A typical paneelabsorber consists of a rigid panel—often wood, gypsum, or metal—backed by a cavity or filled with a porous material such as mineral wool or fiberglass, and finished with a fabric or perforated cover. The precise geometry, material, and backing determine the absorption coefficient and the frequency range of maximum absorption; most standard panel absorbers are most effective in the mid to high frequencies, while low-frequency absorption requires thicker assemblies or additional bass-trapping strategies.

Paneelabsorbers come in various forms, including porous-panel absorbers with a backing cavity, perforated-face panels, or fabric-covered boards with mineral wool cores. They are typically specified by an approximate NRC or Sabins absorption area, and their performance is influenced by installation: surface coverage, spacing from walls, and room geometry. They are commonly used to manage reflections in rooms of different sizes and functions, from studios to multipurpose spaces, and are adaptable to aesthetic considerations through fabric, color, and mounting options.

Applications include recording studios, broadcast rooms, home theaters, classrooms, and performance spaces. They offer a practical balance of acoustic performance, aesthetics, and cost, and are compatible with standard fire-safety requirements when manufactured with appropriate materials and finishes.
