    Flanking - The transmission of sound around a perimeter or through holes within partitions (or barriers) that reduces the otherwise obtainable sound transmission loss of a partition. Examples of flanking paths within buildings are ceiling plena above partitions; ductwork, piping, and electrical conduit penetrations through partitions; back-to-back electrical boxes within partitions, window mullions, etc. Flanking occurs when a free standing partition size is less than the wavelength of sound to be blocked.
