Durkish Corporation
this small manufacturer produced a number of aural detection devices during the era of the Great Sith War. Durkish once produced a series of visual detection systems, but abandoned them in favor of aural systems. The corporation's leaders reasoned that visual systems could be fooled, but aural systems were almost foolproof because every living creature had to breathe. The normal sounds of respiration, even when slowed, could be picked up by aural detection systems.
