Just cause those mythbuster folks couldn't prove it, doesn't mean they're right.

re:'Just cause those mythbuster folks couldn't prove it, doesn't mean they're right' - actually, it does, Science works by repeating an experiment & seeing whether the result confim the hypothesis or not. OK, you may quibble about the rigour of their 'experiments', but the only effective rebuttle is to produce evidence to the contrary... the lack of this confirms Cal's hypothesis...

but the lack of a positive doesn't make a negative. Disco dumps are well documented. Extreme VLF sure makes me queasy and sick.. Add a pouding beat, which the myth guys DID NOT DO, and watch. Or maybe tightly banded VLF noise..

Yes, I very much disagree with the testing they did for the brown note.

And you think that has something to do with the music?

Sure it does, it's jiggling up what you had to drink.

Me too. I wanted to see the **** hit the fan, so to speak.

You remember they used ported 18" PA woofers and then fooled around with port plugs (bungs)

I would like to see Tom Danley test the Brown note phenomena!
A bunch of ported 2x18 will not produce 145 dB @ 8 Hz.

I can see some big shipping containers loaded with Fs =15 Hz Qts= 0.4 high Xmax drivers in a tapped horn. 4 of those stacked should do it, if its doable.

Sorry, no experience. I was really just listing drugs that have been known to frequent discos. I thought that since there are many recorded instances of persons doing the disco dump when simply in anticipation of doing heroin that maybe...
