Building Construction 1

3- Sound Insulation:

Sound insulation describes the reduction in sound across a partition. The sound
insulation across a good conventional, lightweight, office to office construction.
Privacy describes the perceived sound reduction across a wall. Privacy is
a function of both sound insulation and background noise. Background noise is
made up of services noise and environmental noise sources breaking in through the
facade or open windows, vents etc.

Material:
Two of the best soundproofing insulation materials are loose-fill cellulose
and fiberglass. Blown-in insulation provides a twofold benefit, both adding
insulation and soundproofing to your home. This is a perfect twofer, since if
you're trying to reduce noise, you might as well reduce your utility bills!
