Producing infrasound can be quite expensive.

 

These days, you can buy large sub-woofers that have a long action to produce infrasound. You also need a source. You can hook it up through an amp to a signal generator, or buy special CDs that pump out infrasound. Its best to shop around and google for specialist suppliers. Some of the car audio companies are producing powerful infrasonic sub-woofers, so you might start there.

 

Im sure there is a tutorial somewhere online that teaches you how to make your own out of inexpensive materials, but that set-up was nearly 8 meters long.

 

If you use a signal generator for your source, do some research into the effects of strong infrasound first. There are rumblings that using 7Hz can cause death. you dont want it to be THAT scarey, right? You need to find the correct frequency and volume to give an effect, but not make it too uncomfortable for your patrons. It can make people quite sick for days if its too strong.

I don't know much abound Infrasound, but I do know that low frequencies can be VERY dangerous. Effects can range anywhere from ruptured ear drums and nausea to death. Just be careful when experimenting and make sure you have enough knowledge to operate the equipment safely.

i just want the guests to feel like the room is spinning or something. it will only be a short blast, maybe 5-10 seconds, just enough to make them think 'wtf?'

 

so, its basically a very low pitch then?

Mythbusters busted the 7hz myth. 8-10 hertz, however, causes nausea.
