Mass Loaded Vinyl: Key Qualities
Mass Loaded Vinyl (MLV) is used as part of an insulation system, particularly within oil and gas facilities, to dampen sound, reducing noise levels to an acceptable level. The material is one of our key products at BS Stainless, both in its ordinary form and as part of SoundMet, BS Stainless's revolutionary acoustic barrier system.
To understand how MLV achieves such impressive sound insulation, it is helpful to use the analogy of throwing a tennis ball at a sheet that is hanging from a line. When it makes contact, the energy of the ball is transferred to the sheet, which will move freely in three-dimensional space. If the sheet's other edge were secured to the ground, the ball would bounce off, causing the sheet to vibrate.
In our analogy, the tennis ball represents sound and the sheet represents an acoustic barrier. If such a barrier is flexible then sound energy can 'bleed off', resulting in increased net losses of sound propagation as the barrier moves in space.
