Chapter 3.0 Types of acoustic treatment

3.2.2 Sound blockers

Sound blockers prevent sound from entering or leaving a space. Blocking sound can involve introducing dense or heavy structural components during construction like concrete blocks or gypsum boards that increase the structural mass of walls, floors or ceilings. It can also mean introducing vertical ceiling panels or room dividers, sealing gaps between doors or windows, or filling other openings letting noise in with materials like insulation or acoustical sealant. The extent of the measures that need to be taken depends on the amount of noise you wish to block.

  • Mineral wool insulation
  • Resilient channels for decoupling drywall from internal building structure
  • Soundproof drywall
  • Acoustic caulk or sealant

Use to:

  • Reduce amount of sound entering from outside
  • Isolate noise from noisy appliances
