Mass Loaded Vinyl - The Acoustic Solution

Mass loaded vinyl is designed to dampen sound as part of an insulation system, ensuring health and safety regulations regarding noise levels in the workplace are adhered to. BS Stainless are expert suppliers of this flexible sound barrier, which is particularly suited to stainless steel jacketing solutions within gas and oil processing plants.

A good analogy to help understand how mass loaded vinyl achieves its high levels of sound insulation is that of the tennis ball and sheet. A tennis ball thrown at a sheet hanging on a line quickly loses its energy - this is transferred to the sheet which can move freely in three-dimensional space. If the sheet was secured to the ground, the ball would be able to bounce, resulting in vibration of the sheet.

The tennis ball represents sound and the sheet represents the soundproofing material - if the material is limp and flexible then, in accordance with Newton’s Three Laws of Motion, sound energy can be ‘bled off’, resulting in higher net losses of sound propagation as the material moves in three-dimensional space.
