On Sonic Warfare
This is pretty cool. Bldgblog describes how biomimicry plays a role in the deployment of sonic weapons. Using a network of speakers and an annoying recording (much like PSYOP units use), researchers were able to agitate an infestation of beetles to leave of their own accord.
Sonic weapons are particularly interesting because they can permeate the environment. They are systemic as opposed to firearms as acute-problem-solvers. A properly designed sonic defense system can establish fear vectors, direct flows of traffic, and, overall, shape the environment – much in the same way forts in the past relied on wall to do the same.
