Methods
Adding mass: Increasing the density of walls, floors, and ceilings using materials such as heavy drywall, concrete, or mass-loaded vinyl to block sound transmission.
Decoupling: Installing resilient channels, isolation clips, or soundproofing mats to create separation between surfaces and prevent sound vibrations from transferring.
Sealing: Closing gaps, cracks, and openings in walls, windows, and doors to minimize sound leakage.
Adding barriers: Erecting sound barriers such as soundproof curtains, acoustic panels, or double-glazed windows to reduce external noise.
