Not in Nevada but my wife and I hear the sound every single night. There's this website THE HUM where a few researchers say they're trying to get to the root of this. See this great article first though about the people who hear the hum: ARTICLE ABOUT PEOPLE WHO HEAR THE HUM
Interesting stuff! Oh and we live right near Malibu, CA. Can definitely report we hear it EVERY night.

This time of year, if you have humming birds around they make a very high frequency noise or buzzing sound during courtship that resembles the sound of live high current only faster.
This normally happens up in the air above tree level where the sound carries but the tiny bird is fast and hard to see.
Not going to bother with a recording or YouTube link as it's all over if your looking. I plant flowers and have tall trees so the noise is kind of frequent and normal, before I knew ,it freaked me out some.an alarming noise raising in frequency before dropping off?

Vegas here but haven't heard it. Of course it's hot and I have the air on full blast plus my ceiling fan. I wouldn't here it.
What time frame? I'll try to pop my head out of doors tonight and listen.
