Case Study # JS-0516
Description: The client is concerned that airborne noise (conversation, music or T.V. playing), will be entering through the demising wall of the master bedroom in their condo.
Solution: Wall treatment consisting of the following:
• Construct a new wall 1” away from the existing wall from Metal Studs
• Safe & Sound insulation in between the studs (used to absorb sound)
• Install 1lb Mass Loaded Vinyl (this is used to block the transmission of airborne sound)
• 2 layers of 5/8” Type X drywall (this drywall is dense, used for mass & fire proofing)
• Acoustic membrane in between the drywall (provides a barrier to help stop noise and vibration)
• Noise proof caulking around perimeter of drywall (used to seal edges and seams of the drywall and sub floor to maintain the specific Sound Transmission Class (STC) value) Conclusion and After-Effect:
The loss of airborne noise was virtually eliminated, and speech was inaudible.
