dB Absorbers are decorative ceiling and wall acoustic panels manufactured from high quality sound absorbing foam covered with an attractive acoustically transparent fabric.

They are designed primarily to reduce reverberant noise by improving acoustic absorption within the area being treated. When installed directly below the roof space, they will also improve the thermal insulation of a building. dB Absorption panels can be directly bonded to both horizontal and vertical surfaces providing the receiving substrate is in suitably good condition. dB Absorbers are an extremely effective, economic alternative to a full suspended acoustic ceiling and can be installed to create a feature within a room to enhance the interior design.

Sound absorption is defined, as the incident sound that strikes a material that is not reflected back. An open window is an excellent absorber since the sounds passing through the open window are not reflected back. Conversely it makes a poor sound barrier. Painted concrete block is a good sound barrier but will reflect about 97% of the incident sound striking it. When a sound wave hits an acoustical material the sound wave causes the fibers or particles of the absorbing material to vibrate. This vibration causes tiny amounts of heat due to the friction and thus sound absorption is accomplished by way of energy to heat conversion. The more fibrous a material is the better the absorption; conversely denser materials are less absorptive.

The sound absorption coefficient indicates how much of the sound is absorbed in the actual material.
This absorption coefficient varies with the frequency of sound.

Dimensional changes may occur in dB Absorbers dependent on the relative humidity of the area in which they are being installed. Absorbers should therefore be left to acclimatise for 24 hours prior to installation. For best results it is recommended that panels are installed with a minimum 30mm shadow gap between them. dB Absorbers should be bonded directly to horizontal and vertical surfaces in accordance with the adhesive manufacturer’s instructions and subject to the receiving substrate being in suitably good condition.
