Abstract: A method of reducing sound transmission in a building constructed using horizontal cross laminated timber (CLT) panels to provide a floor of the building and a floor assembly are described. In an implementation, the method includes: attaching a plurality of energy transmission control mounts to a ceiling side of one or more of the cross-laminated timber panels using fasteners; attaching a plurality of furring channels to the energy transmission control mounts; and attaching a cross laminated timber sheet to the plurality of furring channels to form an exposed ceiling layer.

Abstract: A ceiling isolation hanger comprises a bracket configured to be secured to an overhead mounting surface. The bracket comprises vibration dampening material configured to bear against the mounting surface, a clip configured to engage and retain a furring channel beneath the mounting surface, and at least one spring element extending between the bracket and the clip.

Abstract: A sound control underlayment having opposed major unfinished floor and floor covering contact surfaces for disposition between an unfinished floor surface and a floor covering comprises a resilient layer and an adhesive layer on at least one major surface of the resilient layer.
