Low droning hum, engine-like noise I will add I do live directly above a natural gas pipeline that runs through the bottom of our little pond, they (not sure what company) put the pipeline in around 2017-18 (30in. Diameter) but the sound started in 2019. I live roughly 6 miles as the bird flys to the interstate, i've lived near it my whole life, when i try to ask my friends or family if they here the hum they generally attribute it to the interstate system, I know that can't be possible, I know what a jake brake or a tire on a rumble strip sounds like and they're not even close to the frequency i hear when i listen to the hum. (I know iv'e included a lot of information but one last bullet point), my whole life I've been able to hear sirens, trains, cars, and horns from long distances away that my peers cannot hear until the noise becomes closer, I'll say "You guys here that? it sounds like a tornado test siren" my friends assume I'm imagining it, then 30 seconds later the sound comes into their range of hearing and I'm proved right. Has happened to me more than 30-40 times in my life(a conservative estimate). I'm not sure if I have an abnormal spectrum of hearing but I do know that I'm awful at listening in conversation but I'm great at focusing on a low or high frequency noises. I hope this helps with plotting data and gathering information. if you have any questions feel free to email this account.
