Sound insulation
Dampening materials are widely used to increase the acoustic insulation rate from any type of walls and surfaces exposed to noise, when these must have a certain level of sound attenuation.
Most often, these materials are applied to walls, ceilings and floors in civil engineering works where its commercial activity may cause noise hotspots in contiguous housing. Another frequent application is, for example, the acoustic treatment in plate enclosures for machine housings.
The dampening materials are heavy and elastic, so they are capable of creating a reflection on sound waves which impact on them and thus they prevent the transmission of noise towards the outside. This is how the desired acoustic insulation is attained.
The necessary acoustic insulation degree in each case can be attained with a higher or lower combination of these materials along with more rigid ones. Such combinations produce the so-called mass-spring effect.
