In a multi-family dwelling, good neighbourliness is often defined in terms of sound control. To muffle sound is a matter of absorbing its energy along its transmission path - in this case, through gypsum board walls. Walls must therefore be built so that their components can vibrate just a little bit here and there so as to dissipate all the energy along the way. Using double studs, wood studs with resilient channels or load-bearing steel studs with resilient channels, increasing the depth of the cavity or filling the cavity with insulation are a few of the ways of controlling sound transmission.
