I think that this is really very interesting on a number of levels. I too have been curious about the reported ability of certain noises to stimulate brain activity.
Can you tell us how you generated the noise? Are there any variables such as frequency balance (low, mid, high) etc. etc. that the user has control over when generating the noise? On first listening the noise is seemingly not random - there is a definite periodicity to it, hence a pitch.
