SPC helps Atlanta highrise solve residents’ noise complaints

Soundproofing Company solves Atlanta condo noise problemsFollowing a recent mandate by the condominium association to reduce neighbor noise, the Soundproofing Company was approached to design flooring solutions for remodels throughout an Atlanta highrise building.

Residents had complained of high levels of sound and impact noise being transmitted from the floors above. They needed a strategy for upgrading the sound isolation characteristics of the existing 6” concrete sub-floor.

The solution in this case was to make use of a semi-decoupled floor using OSB/Plywood layered with Serena Underlay and Green Glue dampening compound. This type of build has resulted in a significant reduction in both impact noise and overall sound transmission.
