Product Details - AcoustiPack LITE PC Soundproofing Kit
AcoustiPack™ LITE (APL)
AcoustiPack™ LITE is a cost-effective multi-layer soundproofing materials kit for standard size and small computer cases, including HTPC's 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.
AcoustiPack™ LITE PC Soundproofing Kit (APL)
These soundproofing materials have been designed to achieve maximum acoustic attenuation over a broad frequency range:
* High Transmission Loss
High transmission loss is the composite material s ability to impede
* High Noise Reduction Coefficients
High noise reduction coefficients is the composite material s ability to
absorb airborne sound energy with minimal reflections.
Damping is the composite material s ability to attenuate structure-borne
vibration on metals and other substrates thereby reducing reradiated
AcoustiPack LITE 2-Layer Materials
AcoustiPack™ LITE contains 2-layer acoustic materials. Comparative small and
large scale acoustic tests with alternative single-layer PC sound-proofing
materials demonstrate that AcoustiPack™ multi-layer materials are more effective
and safer, whilst still remaining as thin as possible.
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 (>1kHz). 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. Acousti
Products 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
