Product Summary

SOS Parabolic Acoustical Listening Systems use innovative technology developed to significantly enhance the ability to hear and identify sounds at distances normally undetectable to the human ear. In addition to extending the effective ‘hearing’ range, the device can selectively filter out unwanted sound frequency ranges.

Extremely light and portable, the 6 inch or 10 inch unit can be paired with the newly developed filter amplification pack (AmpPac®) to create a revolutionary system. This listening system can be used to detect and locate life signs and other critical sounds during rescue operations. Or it can effectively be used for many commercial and mechanical applications.


Potential Applications

  • Police – Enhance SWAT deployment and surveillance operations; monitor crisis situations with more intelligent
  • Firefighters – Locate victims caught in fire and disaster situations with enhanced life-sign detection
  • Search & Rescue – Detect individuals trapped in collapsed buildings, earthquakes or other natural disasters
  • Government – Provide technology to support unique applications for Border Patrol, Homeland Security,
    State Department, Port Authority, DEA, FBI, ATF, Customs, Forest Service and Coast Guard
  • Military – Aid in Target identification, reconnaissance, perimeter surveillance, urban warfare; detect enemy
    presence in caves, houses and distant areas
  • Commercial Industries – Use in detecting specific mechanical noises
  • Power Companies – Augment ability to quickly and easily identify power line faults, coolant leaks and gas
  • Other Applications – Deliver capabilities valuable to public venue crowd evaluation, high-rise stairwell
    monitoring and criminal concealment detection
