Sound absorption

Acoustic absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. Part of the absorbed energy is transformed into  heat and part is transmitted through the absorbing body. The energy transformed into heat is said to have been 'lost'.

When sound waves collides with walls, part of the sound's energy is reflected, part is transmitted, and part is absorbed into the walls. Just as the acoustic energy was transmitted through the air as pressure differentials, the acoustic energy travels through the material which makes up the wall in the same manner. Deformation causes mechanical losses via conversion of part of the sound energy into heat, resulting in acoustic softening

In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators - absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most.

How well a room absorbs sound is quantified by the effective absorption area of the walls, also named total absorption area. This is calculated using its dimensions and the absorptioncoefficients of the walls. The total absorption is expressed in Sabins and is useful in determining the reverberation time of a room.

Sound isolation

Sound insulation or acoustic insulation is the shielding of a room from outside noise. Sometimes also from the inside to the outside (for example a disco).

Sound insulation distinguishes between airborne noise and contact noise. Airborne noise causes the sound to travel through the air. In case of contact noise, the sound spreads through materials.

Because our ear is also a warning organ, soft sound is transmitted well and loud sound is muffled. As a result, the sound perception is not directly proportional to the volume.

SET Frame - Acoustic panels

The SET Frame acoustical panel combines effective sound absorption with aesthetic appeal and provides you with a refined method to address acoustical issues while improving or preserving the aesthetics of the space.

SET Frame's robust aluminum frames, available in three thickness for different acoustical applications, keeps the printed high-resolution image perfectly tensioned throughout the life of the panel. The SET Frame contains a layer of acoustically absorptive material and a smart frame construction for stability. Graphics are printed at very high resolutions on flame retardant fabric.

The SET Frame comes standard with a natural anodised frame including hardware for wall mounting. Frames in white or black powder-coated also available. Printable surface is a maximum of 500 cm wide

Features & benefits

  • Flame retardant print



  • Airports
  • Retail establishments
  • Restaurants and bars
  • Offices, meeting and conference rooms
  • Museums
  • Studio’s




Application - Showroom

To reduce the reverberation of a showroom we installed seveval SET Frame acoustic panels.

In this case the panels are equipped with white fabric to blend in the clean white walls.

Application - Temporary meeting rooms

For a venue that was short of executive business units we provided temporary meeting rooms using the SET Frame - acoustic panels.

The meeting rooms consist of wall and ceiling panels equipped with custom prints.

Transparant panels for the doors and windows give the meetings room an open and friendly experience.

Sound baffles

Our mobile and modular sound baffles are ecological devices which reduces the strength (level) of sound. Sound baffles are a fundamental tool for sound isolation and acoustical improvemnt for events, congresses, concerts, festivals etc.

The sound baffles are designed for standard rigging applications like trusses. Due to the smart and fast connection system it is very easy to create large sound isolating and absorbing surfaces.

Features & benefits

  • High sount isolation coefficient
  • Improves acoustics in reflective spaces
  • Improves speech intelligibility
  • Flame retardant elements
  • Certificated internal rigging parts
  • Easy connection between sound baffles to avoid sound leaks



  • Concerts and festivals
  • Studio’s
  • Events
