There was a time not all that long ago where I worked between day shift and night shift. Night shift meant sleeping during the day. We made lots of changes to the bedroom to make it dark, but we also bought a white noise machine and it would play summer night sounds endlessly. It helped cover up the sounds of an awake world so that I could sleep. We still use one today. But early on if we had a power outage the lack of white noise, even at night, would wake us up. That original machine bit the dust after 30 years but it was quickly replaced with a much smaller machine that is playing for the wife as I type at the keyboard. Unlike the original this one has an internal battery and can go on the road and require nothing more than a charge every few days. The sound we chose for it? I threatened lullabies, but only as a joke. It plays a rainy summer night with crickets and spring peepers. Since it has an internal battery gone is the heads up we'd get when we have a power outage. But the various tracks have a dead area that line up every other hour or so and that results in about 1 1/2 minutes of recorded silence. I've been known to awaken when that occurs. Then it starts the white noise again, all is right with the world, and I'm back to sleep.
I remember those LPs.
