Noise Control - Walls, Floors and Ceilings

Index For Sound Proofing & Noise Control

Problem: Poor noise reduction from a lightweight floor system

Cause: Ceiling directly attached to the floor joists.

Solutions: Use resilient metal furring to support the ceiling as described in the section on Noise Control For Walls, Floors & Ceilings.

  • Do not use nailed wood furring, since the rigid coupling they provide between the floor and the ceiling transmits sound vibrations through them.
  • Double the mass of a drywall ceiling installed on resilient furring to reduce noise transmission. Do not do the same on nailed wood furring - it doses not improve noise control.

Cause: Poor sealing at edges of ceiling

Solutions: Seal the wall-ceiling junction with regular tape and joint compound.
