Industry in shot themselves in the foot by having men in white coats claiming to be scientists spouting whatever suited corporate profits as science. The tobacco industry was the most obvious offender, but they are not the only one. Then they bribed regulators and interfered with science research and publications, bought politicians and funded pseudoscience. They screwed their long term ability to use science in the interests of short term profits.

I don't think that is true, or even possible. It does not generate the sound you are about to hear. That would require prescience. It generates the sound that you have just heard, on the assumption that the next sound will be the same. That's why it works well for fairly continuous background noise.

My backyard is 60 acres and is open to the public. It griefs me how few people take advantage of it. If you're anywhere close to Raleigh North Carolina I'd be happy for you to visit.
