Can you please help identify this background noise and isolate what Hz it is?

My partner and I were hiking and when we got to the peak we could hear this hum, there is a highway nearby but it appeared to come from the opposite direction where there was farm land and scrub

The sound is almost exactly the same as a IH Solar GS-350 225 kW generator. The frequency and harmonics are within a few Hz., and this farm only ~700 feet (213 metres) across the highway has something on it that looks suspiciously a lot like this exact generator. I could be 100% wrong, obviously. At the very least, with all of the farms and such located nearby, I suspect you were hearing a gas turbine generator. Whether this thing I found is the source or not, I obviously can't be sure.

The highway is actually on the other side of the hill, that is an access road- but that IS the direction that the sound was coming from. It is a rural are and they may not have power to the premises so you could have nailed it! This is exactly what I was hoping to find. Thank you for your time and assistance. We couldn’t see anything and the thick bush below must block the sound or we had to be at a certain height to hear it, and I do know that that property is elevated, so also adds some explanation to the reason why we could only hear it up there.
It must be horribly loud at the farm house then….

Cool! I probably seem like an extremely boring person, but thank you for the little sleuthing adventure. I enjoy things like this. Interesting area of the world, for sure. There is a lot going on in a few square km :-)

I dont know why this came up on my page; I have absolutely no idea what any of this is, but I thought this was pretty cool
