The reproduction of a 6hz tone (I guess it could be called a tone)
would be utterly useless. It is completely inaudible.
If you are in a sound field that includes an acoustical signal at 6
Hz, and its intensity is sufficient, you will perceive it. Is it
audible?
Don't you lose control of your bodily functions when exposed to a
frequecy that low?
AFAIK everybody does. Nikola Tesla was an early experimenter who discovered
this effect.
I seem to recall that a crowd control weapon was
thought of using extreme LF. It didn't work because it wasn't
possible to make the frequency directional.
I think they figured that out, too.
