 RadioShack Electronics kit
with Manuals by Forrest M Mims III
having a section referring to the
use of a geigercounter for computer security.
Thames and Kosmos Robotics Kit using Ultrasound/ SONAR control
and has a link for Bluetooth/ SmartPhone control.
A bazooka subwoofer may be used as both a sonic weapon
and a silencer. Reflecting the output to a wider and shallower 
parabolic dish may create a white noise area. Using the same design
without any internal speakers
may allow
the absorbtion and reflection of sound directed towards the users.
I have a small boom tube and a refelector set up
in a few small pine trees. 
It and a few other similar designs
aid and assist in the reflection and
deflecting of sound, 
ultrasound, radio waves, 
and frequencies in the same ranges.
These are
variations of the designs
that the US Army Core of Engineers
shared with me.
Thanks, Ladies and Gents, 
for
everything.
