AcoustiPack LITE is a cost-effective multi-layer soundproofing materials kit for standard size and small computer cases, including HTPCs and SFF cases. Each pack contains 2 large sheets of sound-proofing materials using our unique 4mm (2-layer) acoustic composite. This material is ideal for fitting within the narrow confines of modern enclosures yet it has superb noise reduction capabilities.
2 Layer Materials
The upper layer, immediately opposite the noise source, is a layer of semi-open cell dense acoustic foam which provides a low-reflection surface. This upper layer of foam provides some sound attenuation, especially of higher-frequency sound (>1 kHz). The very dense black limp 'plastic' layer at the base of the 2-layer material is directly attached to the substrate. This layer acts as both an acoustic barrier (effectively attenuating the transmission of sound energy through the material) and as a damping layer, reducing vibration in the substrate (usually a thin steel panel in many PCs and server enclosures).
The 2-layer materials in the AcoustiPack range of kits are 4mm thick. We manufacture thickness greater than 4mm for OEM and manufacturers, but the thickness in the AcoustiPack kits is the thinnest we can produce to facilitate fitting the materials in small and narrow spaces inside modern PC cases.
Features:
An EXTRA sheet of 3-layer acoustic material
Ideal for noisy PC cases where space is available
Pack contains 1 large sheet of soundproofing material
Sheet is 7mm (3-layer) acoustic composite
High transmission loss is the composite material’s ability to impede airborne noise.
Damping is the composite material’s ability to attenuate structure-borne vibration on metals and other substrates thereby reducing re-radiated noise.
The individual components of the multi-layer composites used in AcoustiPack™ sound-proofing kits are certified and UL-listed for low flammability.
The finished 2- and 3-layer composites (including the adhesives) have also been tested using a vertical burning flame test, and both 4mm and 7mm materials meet class UL94-V0. The acoustic foam material supplied in AcoustiPack™ EXTRA is certified to UL94-HF1.
These low flammability results more than satisfy BS EN 60950-1:2002 ‘Information Technology Equipment - Safety’ section 4.7 with respect to resistance to fire for materials inside fire enclosures.
