A “sound barrier” can significantly improve the performance of a well or ceiling. Sound barriers such as mass loaded vinyl (MLV) or a mass loaded rubber work in several ways:
- They add mass which slow down and absorb sound waves
- They are flexible and dissipate the energy in sound waves through microscopic movements when exposed to sound waves
- When installed correctly, they provide an almost-airtight seal of the wall or ceiling, which improves soundproofing performance.
They are also easy to transport and install compare to drywall, which makes them cost effective.
At So Quiet Soundproofing, we use products such as Peacemaker® by Audimute. When Installed correctly, one layer of Peacemaker® can add 10 STC rating points to a typical wall, which is a 50% reduction in perceived sound volumes on the other side of the wall. There are several kinds of Peacemaker:
- The Peacemaker 3.2mm is a denser membrane that works best when sandwiched between studs and drywall panels to block out air-borne sound, which is typically mid- and high-frequency. Peacemaker® sound barrier is a non-toxic, low-emission, LEED eligible material.
- The Peacemaker 6.4mm underlayment is a thicker, less-dense material with superior sound absorbing property, and works best for dampening low-frequency impact sounds traveling through the floor and through or into the building structure.
