Abstract: A system for acoustical performance enhancement, where combinations of component solutions are tested or modeled and given performance ratings. A builder desiring an sound control upgrade forwards project information, such as building plans and the desired performance level, to a design department. The project information is reviewed and a combination of component solutions is determined to increase the performance level of the home to the desired level. The project information is then modified according to the selected combination and presented to the builder. Because the combination of component solutions has been tested and addresses all possible acoustical weak links in the project, confidence of obtaining the final desired performance level in the project is high.

Abstract: A sound-deadening laminate, comprising a structural skin having a first face; and a layer of sound-deadening material, wherein the material has an equivalent Young's Modulus between 50 and 600 psi and is attached to the first face of the structural skin to form a laminate structure. The sound deadening laminate may be attached to framing members of a building.

Abstract: Building component assemblies include a sound-deadening board having defined compressional stiffness positioned between a framing member and an assembly board.

Abstract: An acoustic medium for temporary acoustic treatment of a room is formed from one or more continuous curtains, preferably, with pleated first and second major surfaces. Each pleated curtain preferably has one or more series of collapsible elongated tubular sections which form the pleats that make up the major surfaces of the curtain. Since the elongated tubular sections are collapsible, the curtain can be retracted by collapsing the elongated tubular sections and extended by opening the elongated tubular sections. The mat materials forming the elongated tubular sections and the pleated major surfaces of the curtain provide the curtain with an airflow resistance through the curtain, in a direction generally perpendicular to the planes containing the apexes of the pleats forming the first and second major surfaces of the curtain, that has the desired properties for absorbing or reflecting sound.

Abstract: A sound attenuating wall or ceiling assembly includes: a plurality of wall or ceiling boards; a series of parallel spaced apart, elongated framing members; and a series of elongated sound attenuating members extending along the length of the framing members, secured to the framing members and securing the boards to the framing members. Each of the sound attenuating members has a resilient cantilevered portion to which the boards are secured. The cantilevered portion of each sound attenuating member extends from the framing member to which the sound attenuating member is secured both outward away from the framing member and toward an adjacent framing member whereby the boards are resiliently secured to the framing members and spaced outwardly from the framing members to attenuate sound.
