dB Acoustic Panels 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.
| Thickness | 125Hz | 250Hz | 500Hz | 1000Hz | 2000Hz | 4000Hz |
|---|---|---|---|---|---|---|
| 25mm | 0.05 | 0.27 | 0.68 | 0.89 | 1.00 | 0.94 |
| 50mm | 0.23 | 0.50 | 1.00 | 1.00 | 1.00 | 1.00 |
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.
