Product Details - AcoustiPack LITE PC Soundproofing Kit
AcoustiPackô LITE (APL)
AcoustiPackô 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.
AcoustiPackô 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
AcoustiPackô LITE contains 2-layer acoustic materials. Comparative small and
large scale acoustic tests with alternative single-layer PC sound-proofing
materials demonstrate that AcoustiPackô 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 AcoustiPackô range of kits are 4mm thick. Acousti
Products manufacture thickness greater than 4mm for OEM and manufacturers, but
the thickness in the AcoustiPackô kits is the thinnest we can produce to
facilitate fitting the materials in small and narrow spaces inside modern PC
