One evening, I was sitting alone in the eating area of a very high end office, and noticed a whooshing sound coming from the top edge of the room. I thought it was maybe some air vent, but there was no wind outside. I stuck my phone camera up behind the front lip of a shelf and saw a set of speakers. They were playing something close to brown noise!
And, I learned about sound masking [1]. So, apparently there's two ends to be avoided, in the signal-to-noise problem!
