Alton "Hum"
 

On March 3rd a low frequency hum started up, and has not stopped since.
I live on a hill near the "floating bandstand" It is as if something has gone on-line, such as a steam plant. The hum pulsates, changes pitch and intensity.
It seems to be louder indoors as if travelling through the ground.

We have driven to different locations in Alton such as near Prospect Mt., the Christian campgound and even Gilford.

Has anyone else experienced hearing this hum?

There are excellent articles on the "Hum", it extends beyond Alton.
It is not Sci-Fi

Alton hum
 

Google the Taos hum.

This apparently is a world wide phenomenon that has gone on for years.

Infra-Sound? Wind Farms? Aeolian Mega-Flute?
 

Although "the weather" has been considered in such studies, check the direction and intensity of winds in your area. Strong March winds may have removed the covering of a large round structure, like a silo, a well, or a water tank, producing "standing waves" inside the cavity.

Florida has been installing utility poles made of lightweight composite materials when replacing wood and concrete utility poles. A strong NNE wind in my area causes an annoying low-frequency hum from the only FRP pole in my neighborhood. A long series of paired holes appear along its full length, making it a giant low-frequency flute! :eek2: Except that the hum is not particularly harmonic, the hum could be termed a monotonous "tune".

As the frequency is a low one—and intermittent—it took weeks to find the source was a single pole just down the street! This is a windy spot, so when strong winds come directly from the east, the uppermost wires produce a powerful—even scary—droning.

See Aeolian Harp or Aeolian Flute.

Thanks, ApS, for the very interesting explanation. 🐻

Alton hum wind not a factor
 

I have studied the wind over the past month. It does not seem to matter what the intensity or direction. It is there on calm nights, rainy nights, windy nights.
Not an asthmatic church organ, more like a really bad electronic imitation of one. The pitch ranges from Low c to Low f (most likely overtones from a much lower pitch) and varies in intensity. I feel vibrations from it.
Did not think of telephone poles. You are right, it is very hard to find a source.
One article mentioned that 2 % of the population can hear it. Lucky me!

Anyone else out there with keen hearing?

60 HZ transformer hum?

Alton Monks?

I had a similar hum in Ma. It drove me crazy for a week and my wife couldn't hear it. It would come and go and had me thinking that I might have had some sort of ear damage. Finally at 3 AM, I followed the hum by foot(couldn't hear it in the car) and traced it to a large generator temporarily supplying power to a building that had no electricity due to a flood.A week later, the generator was gone as well as the hum.

Sounds like a good start to a horror movie...

Bingo!! There's transformers everywhere. I'm not saying they're all humming but it certainly is a possibility some are! Any change in the grid could create this.

There are transformers or “ballasts” that I hear when I take my dog for a late walk. The bigger outdoor light have them.

Well, There's This...:
 

Opened an astrophysics page, and found this revelation:

Watch out
 

Criminal minds had an episode about a HUM. It drove people insane...Just saying!

The frequency matters.

South Park had an episode on this.

Don’t search it if you are prim and proper. :laugh:
