I have added binaural beats and "hypnotic" sounds of waves to bring you in a state of alpha brain waves.
Yes. I regularly listen to Brain Sync's Deep Sleep and Sound Sleep. It may be pseudoscience, but it puts me to sleep without fail (within 10-20 mins) everytime I listen to it - which is good enough for me to 'believe'. Or at least want to. Eno's Music for Airports and On Land do the same thing (for me), but on a much more interesting level. ..... Pity about your sig link/possible spam factor, as this could have been a good thread.
ill give this a shot again but ive tried all the get high ones, all the health orientated ones without any effect. people say you need a certain type of speakers.
Binaural tones only work if you have separate L/R channels going directly to each ear. e.g headphones http://en.wikipedia.org/wiki/Binaural_beats
