AcoustiPack ML 3-Layer 12mm OEM Material

Acousti AcoustiPack™ ML 3-Layer 12mm 1000x210mm

This product is one sheet of AcoustiPack ML (multi-layer) 3-layer 12mm thick soundproofing material, dimensions 1000mm x 210 mm  - 38.375" x 8.25".

The range of AcoustiPack™ sound-proofing kits has been designed with customer's pockets and greater flexibility in mind! As a result, Acousti have introduced AcoustiPack™ 3-layer Sheet 12mm), which is a single large sheet of their latest generation acoustic material. This sheet is based around the AcoustiPack ML 3-layer 7mm, but this sheet is 12mm thick. This extra thickness allows for even better noise reduction if space is available. It is supplied as a extra long sheet for those customer who require more material.

Material Features

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 airborne noise.

• High Noise Reduction Coefficients
  

  High noise reduction coefficients is the composite material's ability to absorb airborne sound energy with minimal reflections.

• Damping
  

  Damping is the composite material's ability to attenuate structure-borne vibration on metals and other substrates thereby reducing reradiated noise.

AcoustiPack ULTIMATE 3-Layer Materials

In our latest generation of 3-layer composite (Patent Pending), the dense acoustic barrier layer has been 'suspended' away from the substrate in the center of the acoustic foam. The construction layering is like this: (noise source) acoustic foam -> acoustic barrier -> acoustic foam (then the substrate, which is usually a metal sheet panel).

AcoustiProducts 3-layer acoustic material design.

Sound energy first hits the upper foam surface, which is similar to the 2-layer construction, in that it is a low-reflective soundproofing material that is particularly effective at absorbing high frequencies. The sound energy then encounters the central suspended barrier layer, which is decoupled from the substrate. This high-density high-mass layer acts as an acoustic barrier mass to the transmission of energy through the material. The 3rd layer of foam acts to suspend the barrier layer a small distance away from the substrate. We have found from both small scale impedance tube and larger scale reverberation chamber acoustic tests that the 'suspended' central acoustic barrier effectively increases the absorption of low frequency noise (<1kHz). This may well be a result of the 'mass-spring effect', where low frequency energy is absorbed by the sound 'moving' the layer when it is excited by certain resonant frequencies.

The 3-layer materials are attached by a supported self-adhesive directly to the substrate, and have a damping effect on panel vibrations. (Hit the side of your PC once fitted, and you will hear a dull 'thud' sound).

Suitability

Designed for industrial uses.

Perhaps best suited where there is enough room to fit a sheet of acoustic materials that is 12mm thick. Best fitted directly opposite a noise source, such as adjacent to the CPU fan on the inside of the case side door panel, or on the floor directly below a noisy HDD cage.
