Explanation of Flanking

What is Flanking?

Flanking is when sound vibrations pass through a structure along an indirect path. These paths are most common through framing connections, electrical outlets, recessed lights, plumbing pipes, and duct. Lab tests cannot account for flanking and should not because of the varying levels of flanking in any assembly, however, in the field flanking cannot be ignored. With enough flanking, the performance gains of sound isolation products can be entirely lost.
