So, the 10 million dollar question: Does it work? Well, I’ve tried a “meditation” preset and a “coffee break” preset and I have to say, I was stunned. The names of some of the files are very compelling out there. Note: you HAVE to use headphones for bianural beats to work, preferably good quality headphones. They even have a forum for binaural beat enthusiasts here – they have more files for download here. You can also direct download a sample: ogg binaural file (playable on Chrome browser). OK so you’re too lazy to use the Google, so this one will get you started. If you look around, you’ll find a number of sites where you can download other presets as well. There is an open source piece of software called SbaGen that you can download that will play the binaural files through headphones and it comes with a number of presets. There are a couple of companies that sell the software and the files for it (usually for about $5 apiece), but I’ve found a free version. Some say that it works so well that you can recreate the effects of meditation, happiness, and even the effects of certain drugs, all without leaving the comfort of your own headphones. The imaginary beat frequency manages to somehow force your brain to start taking on the frequency of the beat frequency (I guess based on some sort of resonance or interference concept) and people are using this idea to actually modify their mood and mental state. The interesting thing is that these perceived beat frequencies cause your brain to do some strange things. As it turns out, if you play these 2 frequencies separately into your 2 different ears, your brain tries to resolve the difference between the 2 frequencies and “hears” the beat frequency even though it isn’t there. If you play 2 sound waves that are very close in frequency (but not quite exactly the same), you’ll get a phenomenon that causes beat frequencies between the 2 sound waves.
