Introduction to soundproofing materials

An introduction to the materials commonly used in soundproofing.


Effective soundproofing can only be provided by materials which reflect sound energy.

Such materials would be massive and non-porous, such as concrete, or a well-made brick or blockwork wall.

Here is a list of suitable materials:

  • Concrete
  • Bricks or non-porous blocks
  • Plasterboard (also known as drywall, sheetrock, wallboard, & gypsum board)
  • Plywood and dense particle board
  • Glass
  • Metal
  • Proprietary flexible soundproofing materials

The two characteristics that all of these have in common is mass and non-porosity.

The last item, 'proprietary flexible soundproofing materials' covers an immense range of potential solutions, some of which - when you look at their advertising material - seem to work by magic rather than physics.

They will only work if they are massive and non-porous - simple as that.
