A question about high tension power line noises
Advertisement
My husband and I are having an ongoing debate about a certain noise.

He says it is frogs.

I insist it is coming from the high tension power lines about a half mile from my house.

The reason I'm sure I'm right is because I've heard the noise several times at several different points in my commute.

Being the kind of person that I am, having heard the noise more than once, I immediately slow down when I hear it. One place where I hear it sometimes is at a railroad crossing, and the other places are random places in the woods. At a couple of those places, you can see the power lines cutting through the woods.

More than once, when I drove past our nearest power lines, the noise was almost deafening. It is not always happening - just sometimes.

It sounds like frogs or locusts, but it has a more of a metallic "din" and I think it is more high pitched than frogs, and it loops.

I've googled, but my results mention a buzzing noise, and this is a high pitched looping noise.

Is this a noise that comes from an alarm on the power lines of something? Does anyone know?

Hubby never lets me finish explaining "WHY" I'm convinced that it comes from the power lines, because my explanation starts to sound a little woowoo somewhere around day 2 of my investigations. I'd love to have something to print out and hand to him as proof.

But then again, maybe it's frogs. Do frogs like to hang out near high tension power lines?

Thanks! Heartflowers

I've been around lines that chirp like what you hear. I searched youtube and found only what you did. But I was stunned at some of the noise recorded in residential areas in the videos, and to think that those lines stretch for miles. No wonder people are confused.

They always sound like crackling to me. But you may be able to hear part of the spectrum that is out of most peoples range.
Try recording it and import the file into Audacity. Then you can show your husband that the audio wave is there.
Also an increase in humidity will amplify the noise.
I always hear better right after a rain.

It's possible that what you hear could be some form of Aeolian vibration, when wind vibrates the wires. Here's an example specifically the 2:20 mark:

RE: A question about high tension power line noises
I haven't noticed that frogs like power lines and I am not sure what it is that you are hearing, but I do know that those big transmission tower lines hum at 60 cps, known as mains hum. I've never heard any other sound from them, but I know that the high voltage lines at the top of our rural power lines crackle and buzz when the north wind blows.

Pacific tree frogs, in which we have a great abundance, are powerfully loud for such a tiny little croakers...but I don't know what type of frog you are talking about.

I know that if you approach a large group of them in chorus the sound will deafen you and cause all sorts of harmonics and phantom buzzing tones to be heard. Perhaps that is what you are hearing?

Aeolian vibration FTW.

I leaned something new today, thank you BF! Heartflowers What I am hearing from my high voltage lines may be related to this phenomenon. I've never been around the big transmission lines long enough to hear it, but it makes sense how and why it happens.

RE: A question about high tension power line noises
Just asked hubby, he runs an energy substation so he knows all about this...yes. High tension power lines do make buzzing sounds, he can confirm that.

I learned too! I was just reading up on it and apparently it doesn't take much of a breeze at all to get a good resonance going. I'm sure this is what I've heard that sounds likes chirps and whatnot.

I think you mean high voltage not high tension.

Do frogs like to hang out near high tension power lines?

No. Frogs are amphibious creatures who have an outer layer of skin that they can't let dry out (or they could die) - which is why they feel slimy, and ergo require a source of water (either a river or a pond - puddles aren't permanent enough to sustain them). Given the towers have to be built on solid ground to remain stable (notably, if I recall correctly, with a concrete base), the environment would be completely unsuitable to frogs given there should not be any unstable ground (EG pond, saturated ground) near it (with the rare exception if the towers are near rivers).

Would be really nice to get rid of some of the OCD here.

You wouldn't hear the transmission lines from 1/2 mile away

RE: A question about high tension power line noises
Thank you all so much. Heartflowers

It might be Aeolian vibration ...

My built in speakers are so weak I can't make out the noise in the video :-( but I will check as soon as I get home.

I can tell you that the noise is more intense than the video ... because you would be able clearly to hear it over the wind (I can hear the loudest wind in the video). It's very VERY loud, which is why I thought it was an alarm. The first tiem I heard it was near railroad tracks, and thinking it was an alarm, I was very cautious crossing.

It sounds like thousands of crickets chirping in unison inside a metal box.

If we lived closer to it, it would drive me batty.

My husband is an RF Engineer, so I thought he would know ... but he thinks I'm nuts. I'm going to steal his equipment to research it. chuckle

Thanks. But it's not a buzz - it's like a looping alarm.
