Danley Labs has built high-power infrasonic sources for military weaponry usage. 105dB at 250 meters. Probably $50,000 or $100,000. See link below:

Lord I'll have to start saving up the dough! Have to leave that stuff to the military guys. I'd like to achieve that kind of sound pressure but not at that distance. Hopefully I'll be able to find a less expensive route to get my project going.

Beals Brothers in New York were asked to create 7hz at enough amplitude to make people on the ground lose control of their sphincter muscle by a "government agency". This is back in the early 90's. Danley is the real deal for LF.

  Shoot, I'd like to keep my bowels just where they are but I'll take Danley as a reference. Is this a person here on the a asylum board or possibly a manufacturer?
