It's common knowledge that a background of white noise tends to obscure other noise from outside the house and bedroom that can interfere with sleep.

I had never tried it, but decided to give it a go with a few dozen audio files borrowed from your site. I filled up a 700 megabyte CD with white noise, tweaked it to emphasize the lower frequencies, and had it set to repeat. The results were much more satisfactory than the next best audio background I had: a recording of ocean surf. Thank you for giving me a better day's sleep! (I work at night.)

Thank you for offering the random number generator. I have used it for a research on the effects of target specific communications in a N=2000 population of Dutch War Veterans. In the experimental setting it was necessary to randomise the research population and to divide them over four sub-groups, similar in size. The only acceptable way was to do so by adding a randomised variable in SPSS. Afterwards it was possible to assign the subjects to one of the groups by sorting on the randomized variable. Of course I gave due credit in the report by mentioning your service and revealing the URL.
