Many factors influence the acoustical performance of gypsum board partition systems.
Air cavities, resilient members, sealant details, and various types of acoustical insulation are some of the variables that have a significant effect. Tests were conducted with a variety of partition designs. The acoustical benefits of cavity insulation as well as the effects of insulation density vary with frequency, the basic partition design and the insulation thickness. The effect of insulation density on acoustical performance must be determined for each partition design. With any of these sound sources, the degree of privacy that will be achieved with a given partition can be evaluated simply.
