Incipient mass hysteria....

Certain types of alarm monitoring systems regularly ping to check the integrity of the line.

How long has this been going on? If it is a phone, you can wait until the battery dies and it should stop. Is it coming from an attic space? Have you investigated up there? Does it seem to come from exactly the same place every time, or does it seem to move? Do you have access to a stethoscope for listening to it after it goes off to see if you can track it down? If it is metal, perhaps a stud finder would indicate where it is. Once you locate it, are you willing/able to cut a hole in the wall/ceiling to try and retrieve it? Are there older kids who would take this on as a mystery to solve? Offer a reward to them for solving the dilemma!

The first time we noticed it was this April and it happened on the Thurs morning, then Fri morning, then the following Monday etc. and it carried on like this from all of April till end of May. Then June was silent, until we heard it again this past Friday and Monday. It sounds like it's coming from between the walls and ceiling and when we looked into the attic we didn't see anything. It comes from the exact same place every time between the hours I mentioned before. our neighours in the semi aren't even attached there, so it would be strange that if it WERE their alarm, we would hear that and not their TV that hangs on a shared wall.

It may be some old "relic" electronics with its own power source. Could be linked to HVAC or alarm system. Is this a new house? Has anyone been there working on the house? Could be connected to a hard line phone and still drawing power. If you have a phone like that in the house, you might disconnect it for a couple of nights to see if that stops it. Worst case, it might be nefarious electronics that are broadcasting.

What is a semi?

The only thing we can think of is right outside our bedroom window is the hydro hookup line to our metre, so we thought it would be a sound like that or the old phone line you suggested, but not sure that would be so recurring to ring off every Mon and Thursday at exactly 7:15, 6:30 etc. It's an older home from the 60s.

A semi, or semi-detached home, is I think a single duplex (I'm Canadian and we only say semi, haha).

A smart meter here will make all the radios in the house buzz every time it pings.

I think your house is haunted and that somebody from the other world is phoning to have a chat with the former residents.

(When I was a kid we lived in a house not far from AM radio transmission towers. We could sometimes hear the radio broadcast emanating from inside my parents' bathroom wall.)

I have similar sound in my house. Could it be electrical?

Try eliminating possibilities one at a time. Turn off the power to your house just before the reoccurring sound.

We found the source of our buzzing noise. My husband got a new iPhone but left his LG G7 plugged in, underneath a stack of paper and touching the desk. The buzzing was the Covid lockdown alert from a few days ago.

Me and my husband here the same thing randomly we can be on our phones next to each other and it sounds like a 3rd phone vibrates either in the couch or in bed. We cant figure out what it is we have even moved homes and its still there. We have checked all of our phones and they are dead except our 2 and this has been happening for 2 years now....

Lol omg, the noise moved with you? That's not suspicious at all, and extremely normal.

@Linda McReynolds we are thinking it was the electrical box hookup to the phone wires, that seems to be the only thing because it's not in the walls or attic. Good luck finding your noise!

The same exact thing is happening in my house. It started in April and happens around 6:30 am ... exactly how you described it. We cannot figure it out!!! We live in New England. I'm starting to wonder if its some kind of animal that comes back at the same time every morning. But it sounds more powerful than a sound an animal could make (woodpecker, hornets, etc).

@Amy Michaluk it's so strange because it's exactly timed for us. At first we thought some kind of animal but there's so way they have impeccable timing like that. I hope you figure it out, our phone line cable hookup is right outside where we hear it so we think it might be a weird ping from the phone company.nge because it's exactly timed for us.

In the olden days, my cable tv provider used to “read my box” to bill me for movies. To me, it was a “fan sound”.

My Dish Sat boxes do the same thing daily - and it updates the Guide and updates software if required.

The box's hard drive can be heard spinning up and it lasts maybe 5-10 minutes. I have it set to update in the wee hours daily.

I live in New Hampshire and this has been happening in my camper randomly. I put my hand against the wall and it's definitely a ultrasonic vibration... But I sware I heard something moving around in the wall... So what creature can move in inch thin walls and vibrate super fast?

5g, anyone? Seems no coincidence. Very disturbing

• So what creature can move in inch thin walls and vibrate super fast?

A bee... or maybe a bee with a new iPhone???

We have been going through some thing very similiar we are from Texas. It started when we first moved into this house in the country it was Sept 2018 during that first month we at heard it several times it was felt by my daughter in her room and by myself in my room and both my husband and i both have heard it while together. We all agree it sounds like the vibration of a cell phone. However our is random and sporatic. 2018 a good 12 random times and only consecutive 2 or 3 of those time. Then there was nothing for a good 9 months then out of the blue it happens a few more times this would

be 2019 then again in 2020 but only twice that we known of. Now for 2021 nothing up until right now. It sounded from the same location and only 1 intrival of the vibration as if the cell phone was only called once and not back to back. Still as stumped as ever no land line connected nor cable just 3G and 5G wifi.

I am experiencing the same thing!! 6.30am to 7.30am in the morning, a bzzt bzzt vibrating tone akin to an incoming cell phone call when on vibrate mode! I checked both me and my husband's mobile devices but all of them were on silent (no vibrate mode)! It happened again today morning and the freaky thing is that it was SO CLEAR when I put my ear to the wall.... the sound was loudest in the master bedroom and kind of faded off when I went to the living room to check.

Btw, I live in Singapore (asia) in a high rise apartment. So it's freaking me out to see the same thing happening to other people at similar timings but across the globe.

Next door neighbor's cell phone next to wall?

@stax nope.. my bedroom isn't next to my neighbour's wall :') literally no neighbours around my bedroom layout. Only above and below ):

Found the source of the noise! I moved into a small ranch house about 3 months ago. I'm in Maine, and it was October when I moved in. I was hearing an intermittent buzzing noise in the smaller bedroom that I use as an office. It was in an exterior wall. It sounded very much like the sounds reported here. Kind of like a cell phone vibrating in the wall, or like someone was using a weed whacker... also had elements like a drilling sound. None of those totally describes it, but there were elements of all of those sounds in the noise. It was driving me nuts. But I didn't think it was electrical - it was too loud for that. Also, there were no pipes in that wall, and my power/cable lines and electric meter were at the other end of the house. So not that... Last night it was doing it a lot. So I went to the window and looked outside. It was a very windy and bitterly cold night in January, and I noticed a draft coming in under the window. I noticed that although the window was closed, it wasn't latched. So I closed the latch. The noise stopped!!! I think when the wind blew in a certain direction, it was vibrating the window which was then vibrating the wall, or some element inside the wall! I don't think it had anything to do with the cold, as it started doing it in October. I think it was caused by the wind. Closing the latch firmed up the contact of the window to the frame and stopped it from vibrating. Not sure if this is what's causing it for other folks, but it was definitely caused by the wind for me. Hope this helps others out!

I just now heard a buzzing noise in my room but it isnt my phone. It sounds as if its in the closet. Im scared to go in my room and my little brother is in there

Hot water heater

Pennywise.... :(

OOrLord Jesus thought i was losing it, i had a drug interaction and couldnt sleep for like 40 hours and i thought there was a phone viberating i tore my room apart found it is coming from the wall i recorded because everyone thought i had lost my mind i even hear it through loud music what is it and how do i make it stop

Radon mitigation system? Sometimes the fan makes a low intermittent humming sound when it is wearing out.

Northern flickers are pecking at your chimney. Sound is travelling. It's a mating call. Happened to us sounded like it was coming from hot water heater

So im being stalked weird stalking from the police i think i hear drilling sounds in the wall sometimes I think its some type of weird technology it makes my skin crawl… feels like some type of electric charge. like electricity in the air. how tgey do this undetected, no idea

joef:

What makes you believe the police are stalking you please?

photonic quantum computer weapon. I've experienced this at two different new build condos and it would happen at the same time everyday... light hum or drilling sound, but sometimes very weird hypnotic or even musical.

it's used for gang stalking, please be careful and keep the mind strong.

i believe they're hidden in many condos and hotels.. to create a quantum tether to each person, to allow the harassers to essentially create a virtual environment around you, walk around you invisibly and able to steal your credentials by what's viewed on your screen. they're also able to achieve voice to skull, brain scanning and manipulation. to create a password that cannot be easily stolen, is to use a password generator and move most of the browser off of the screen so the newly generated pw is not "seen".

from google:

"The sound of a quantum computer during cooling is primarily the humming and mechanical whirring of cryogenic refrigeration systems, such as dilution refrigerators, which cool the quantum processor to temperatures near absolute zero (around 50 millikelvin, or -459°F). This extreme cold is essential to stabilize qubits—made of materials like niobium, silicon, and aluminum—so they can maintain fragile quantum states. "

Ooooookaaaay.....
