ACOUSTIC INSULATION
Sound absorption
Sound is reflected by hard materials. Soft, porous materials are best suited for sound absorption. A
combination of different materials can reduce the reflection of sound.
Contact noise insulation
Sound travels very easily through hard materials. Soft rubber material can be used to reduce contact
noise. The effect of this insulation strongly depends on:
–
installation method: make sure that vibrations cannot be transferred between different elements,
e.g. between the built-in heaters and other metallic parts, through pipes, along air ducts etc.
–
installation of acoustic insulation in hollow acoustic spaces. Avoid cavities between insulation and
pipes.
