Sound absorption

How sound behaves in a room

When a sound wave hits a surface, part of the energy is reflected, the material absorbs part of it and the rest is transmitted. The quality of sound absorption is determined by the layout of the space and the materials used.

By nature, stone wool offers excellent sound absorption properties.

Proper sound absorption

  • Sound absorption controls the ambient sound pressure level in a room to create comfortable environments in which people can concentrate and work productively without noise-induced irritation or stress.
  • It increases speech intelligibility making presentation and conversation easier to understand.
  • It reduces reverberation (echoes) and the ‘cocktail party’ effect where sound levels rise uncontrolled in a room as people talk louder and louder to make themselves heard until everyone is shouting.
