CASE STUDIES

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 The shared wall between two neighbours.

Solution: Wall treatment consisting of the following:

• Laminate 1 layer of 5/8” Type X drywall with a viscous elastic dampening compound
(this drywall is dense, used for mass & fire proofing and the dampening compound dissipates structural vibrations)

• Install sound control sealant around perimeter of drywall (used to seal the perimeter of the drywall)

Good Option

Conclusion and After-Effect: The loss of airborne noise was virtually eliminated, and speech was inaudible.

• Install sound absorbing insulation in between the studs (used to absorb sound)

• Laminate 2 layers of 5/8” Type X drywall with a viscous elastic dampening compound
(this drywall is dense, used for mass & fire proofing and the dampening compound dissipates structural vibrations)

• Install sound control sealant around perimeter of drywall (used to seal the perimeter of the drywall)

Better Option

Conclusion and After-Effect: The loss of airborne noise was virtually eliminated, and speech was inaudible.

• Install sound absorbing insulation in between the studs (used to absorb sound)

• Install sound isolation clips, & furring channels (used to de-couple drywall from studs or joists)

• Laminate 2 layers of 5/8” Type X drywall with a viscous elastic dampening compound
(this drywall is dense, used for mass & fire proofing and the dampening compound dissipates structural vibrations)

• Install sound control sealant around perimeter of drywall (used to seal the perimeter of the drywall)

Best Option

Conclusion and After-Effect: The loss of airborne and impact noise was virtually eliminated, and speech was inaudible.
