Ganzfeld Meditation Applet
The ganzfeld (German for "whole field") experiments are a series of parapsychology experiments in which participants are placed in a state of visual and auditory sensory deprivation so that superior psi results can be achieved. In the spirit of the ganzfeld experiments, I introduce the Ganzfeld Meditation Applet.
Rather than the traditional ganzfeld approach of flooding the eyes with red light, and the ears with white noise, this applet is designed to use your vision and hearing to draw you into a meditative state. It displays an image which draws you mentally forward, while simultaneously producing a binaural beat combined with white noise to induce a meditative state and reduce the effects of distraction. For more detail on meditation and its role in psi, please read the Focal Meditation
To obtain the full benefit of the binaural beat, I recommend that you use this applet with headphones. If you want to link to this applet, please link to this page so that people can read the description of the applet.
If the applet does not load for you, it is likely that you need to download and install a new version of Java, which you can obtain from this link

. Sit comfortably, relax, stare at the center, and allow your mind to reach a focused state.
Update April 20, 2006 - Added progressive relaxation.
( Edit Sept. 28, 2008 - In the interest of sharing information, for those who are mathematically inclined I will describe the way the sound is generated. This paragraph is only for those curious or who are attempting to replicate the sound. Initially, the left channel contains a 99 Hz signal plus a 201 Hz signal, while the right channel contains a 101 Hz signal plus a 199 Hz signal. This produces two 2 Hz beat frequencies, one left-going and one right-going (for balance). The progressive relaxation is obtained by decreasing the two beat frequencies linearly over a 170 second time period down to 0.3 Hz. This is then combined with a white noise signal produced by a random signed perturbation of a signal damped by a 0.98 factor 192,000 times per second. For the second stage of the progressive relaxation, over an additional 120 second time period, the volume of the white noise increases by 33%, while the volume of the beat frequencies decreases by 50%. This sound formula was obtained by consideration of the cognitive effects, trial and error, and user feedback. )
Update Aug. 12, 2010 - The left-going and right-going binaural beats are now 180 degrees out of phase for an internal oscillatory effect.
