Exactly.

I actually just went in to Ardour and edited down that one "20 Hz" video I mentioned made me feel weird [1] so that it played the loudest part continuously instead of fading in and out, and then listened to it again and after 5 or 10 minutes of listening to it I felt really weird again, and started to get worried about what it might be doing to me, so I stopped.

It's really interesting, though, and I hope some serious research is conducted on this sort of sound's psychological effects.

Oh god, yes, and it isn't even new. Back around 2005, I ran into a web site selling audio files which they claimed would cure addictions, attract romantic partners, improve luck...

Perhaps the binaural effect does have some benefits, but personally I was struggling to listen to that video for more than 30 seconds or so without feeling both mildly sick and annoyed at the same time! However, I've been listening to the 40 hertz tone from the link I posted above for a good 10 minutes now without any bother. It's quite relaxing after a while actually.
