George Noory played it as part of his show intro last night. My hearing is so gone from years of shooting and wearing headphones, I couldn't hear it. In the snippet posted it sounds like insects, which are plentiful and loud in the tropics.
If the govt. needs a sonic weapons immune "Man In Havana" I'm their guy. I'll need a cigar allowance and heavy duty air conditioners with generator backup. A pallet and refrigerator box for my assistant Mr. A.F. will also be required. If it's crickets I know a guy in Texas, code named "Shackleford", who can deal with them.
They should be glad it wasn't the "Brown Note".
