Sound isolation fails mainly through flanking paths like pipes and air leaks.

Evidence

Flanking paths, which are the main limitation to sound-isolating structures, arise when there are other paths that the sound can travel through in order to get around, that is, flank, the sound isolating structure, as shown in Figure 6.57. Typical paths for flanking are the building structure, heating pipes, and, most commonly, ventilation systems or air leaks. The effect of the building structure can be reduced by building a “floating room,” as shown in Figure 6.58, which removes the effect of the building structure by floating the room on springs away from it. — David M.
