A quick google search will reveal much info on the so called “Brown Noise”. Listening to it is supposed to make you sh*t yourself. It works by using a really low frequency on your speakers (so a sub woofer would be useful, but not 100% necessary).
However, after trying a few different files of it and having my sub on full volume, there seems to be no effect. Does it work on any of you?
P.S. If you try this you would probably be best to have toilet access. (And I cannot be held responsible for any consequences).
