Separating floors are designed to limit or insulate against airborne sound, such as from speakers and impact sounds such as footsteps. The heavier the floor, the less sound is transmitted. Mass is designed into floors by using concrete or adding layers of dense material to the steel floor structure. The physical separation of a floor reduces the transmission of sound through a structure. The installation of a floating floor, which incorporates resilient layers and uses soft or acoustic floor coverings, is the best option for achieving the perfect soundproofing seal.
