Construction Site Noise Barriers: Sound Absorption Solutions

How it works ?

The noise reduction process in a barrier that combines MLV (Mass Loaded Vinyl), polyester insulation, waterproof PVC, and fiberglass involves both sound absorption and reflection. Here’s how each layer contributes:

MLV (Mass Loaded Vinyl) adds mass to the barrier, which helps block sound waves from passing through by reflecting them back towards their source. This layer is crucial for reducing the transmission of sound due to its high mass-to-thickness ratio.

Polyester Insulation is effective at absorbing sound. The fibrous nature of polyester traps and disrupts sound waves, converting their energy into heat and thereby reducing the noise that penetrates the barrier.

Waterproof PVC, while primarily providing environmental protection, also contributes to noise reduction. Its density and rigidity can reflect some sound waves, adding an extra layer of sound blocking.

Fiberglass on the back side acts as an additional absorber. It catches any sound waves that make it through the previous layers, further reducing noise by breaking up and absorbing these waves.

Together, these materials create a barrier that is very effective at reducing noise through a combination of blocking and absorbing sound. This makes environments quieter by significantly lowering the level of unwanted noise.
