Resilient channels have long been a popular, cost-effective component of acoustical design strategies in commercial and multi-family construction projects. They function as de-couplers, permitting the attachment of gypsum board to the framing members without any actual contact between the two components. This separation of the gypsum board from the studs impedes the transmission of airborne sound waves through the wall assembly by breaking their path.
However, in order to achieve maximum acoustical performance from building assemblies that utilize resilient channels, a variety of factors must first be considered. Research done over the years by acousticians, such as Veneklasen Associates,¹ of Santa Monica, Calif., have shown that resilient channel design selection and installation practices can significantly impact a wall, ceiling or floor assembly’s overall acoustical performance.
