It has been hypothesized that high-intensity low-frequency sound (20- 100 Hz) and infrasound (below 20 Hz) could incapacitate personnel located within buildings or underground facilities. A unique reverberant resonant chamber was designed and constructed of reinforced concrete, and incorporated a moveable wall to allow tuning to specific frequencies. Two minipigs (Sus scrofa) were trained to press a panel for food delivery. The tuning wall was positioned to create standing waves ...
To determine if narrow-band, high-intensity acoustic energy in the audible frequency range could be used as a non-lethal weapon, four acoustic devices were tested: (a) a compressed-air-driven siren (CADS); (b) a combustion- driven siren (the Dismounted Battlefield Battle Laboratory, or DBBL); (c) an impulsive acoustic device, the Sequential Arc Discharge Acoustic Generator (SADAG); and (d) a complex waveform generator, the Gayl Blaster. The Primate Equilibrium Platform (PEP) is a continuous, ...
