For years I have left a radio on an unused frequency, just the ambient noise
and static crashes. I started doing this as a kid. I didn't know why it
helped me sleep so well but it did.
Then I walked into a Sharper Image one day and find they called them "white
noise sleep enhancers."
Why didn't I think of that?
A diode switching on and off generates broadband white noise.
So does tuning an FM radio between stations.
