Sonic Detectors?

[Mendrugo]

In "Decision at Thunder Rift," Grayson worries the bandits will have "sonic detectors" that use computer-controlled filters to eliminate background noise and pick up even a whispered conversation. 

As far back as TRO:3026, we had rules for various kinds of remote sensors - seismic, heat, motion, etc., and the AToW ruleset adds radar and trip-line, while the old Tactical Handbook had MagRes sensors.  I've never seen RPG or other rules for the kind of sonic detectors mentioned in Decision at Thunder Rift. 

Have I overlooked something?

Hi,

Closest I can think of is the "shotgun microphone", and I think there was another device that could read vibrations on glass, so they could listen through a window. Both for RPG-scale items, used back in the Third Edition rules.

Thanks,
