Detecting ultrasound, 21-22 khz, 25-65 dB, for last 24 hours

should mention south too.

wind blowing through cracks in your windows

Please give us your theories, I have the feeling that we don t have much time...

lol, no. I hear exactly what the ultrasound detector is registering. I've been listening and watching so much that I'm getting good at guessing the dB level.

I also have a digital audio recorder (capable of 320k sample raw recordings) with condenser mics and it registeres this sounds on line meter but sounds crackly when played back. Maybe that's just how the speaker reacts that frequency, or software, not sure. Haven't looked at the waveform itself. My Android phone and that app I mentioned above work well, and I have another device with analog meters that detect it too.

Now here's a strange thing too. A few days ago when I started monitoring this closely, I would start downloading or uploading a file over WiFi. When I would begin that, within maybe 5 to 10 or 15 seconds later, that ultrasound would stop or reduce itself. So .... whomever is doing this is monitoring the airwaves around here and noticed the relationship to my wifi traffic and what they were up to. They now know I'm onto them. And if that wasn't enough, wifi sniffing revealed someone was de-authentication (disconnecting) people's wifi connections in the neighborhood too.

Someone is messing with everyone in this neighborhood BIG TIME. ??

There's been some other suspicious stuff going on too, such as hacked apps getting into my phone. I track that back to a mysterious edge server. When updating, everything that came from that server was not the same as if fetched from Google or other edge servers. The app appeared altered. Files did not match.

I had someone getting into my wifi via MITM attacks. That stopped when I upgraded my access point to a Synology RT2600ac and started using PMF-ONLY connections, which basically only my latest client services support.

I dump COMCAST when I noticed too much hacking going on. Someone got into 2 Cisco routers of mine and disabled the clock somehow which made it easy to get in after that. It screwed up logging too. And I'm not the only victim. I've sniffed this activity going on here.

I had to buy 2 Fing boxes to keep someone out of my MiFi boxes. Someone was getting in and pretending to be the router.

Man, I have a list of so many crazy things happening since I moved in here, and it's only getting worse. And ... we're on shelter in place orders and I won't go anywhere right now because I'm high risk being over 60 and I had a lung infection 12 years ago that required a thoracotomy operation and 10 days in the hospital. My lungs already have some scaring because of that. So I'm kind of stuck here. I do have an RV but still cold outside, I don't like going when it's cold, but it is warming. I could escape to a campground somewhere, assuming any will be open soon.

Crazy crap. Unbelievable. Complete mystery. I've run out of conspiracy theory ideas for this one. LOL

not tinnitus ?

ie you can travel 30 miles away and do not hear it ?

I thought the "hum" is the shuman resonance ?

Was there a point that you didn't hear detect it and started to? e.g. is there a baseline period where it was not detected? Is this in your house, outside, etc...? Is it all hours? All days?

I scoped the signal and it's just this random oscillation that fluctuates in intensity and frequency, but not by a lot. If I had to name what I'm looking at, I'd call it the concert of ultrasonic violins.

Down converted, and spread out between 600Hz low, 3000Hz high, it sounds f'n creepy chilling to listen too. If I heard THAT late at night while outside, alone, in the dark, I would probably freak out, lol.

I'm just boggled ...

ALSO, it is coming from multiple emitters and it's causing binaural beats. Now THAT is .. alarming.

I'm not kidding about any of this. I'm hearing it and watching it on hardware !! It's happening. Just what is going on and should I be alarmed? Concerned? What effect will this have on me?

The signal is still at between 32-34dB inside anywhere and fluctuating around 22kHz. But last night is was disturbing, alarming, when it would climb past 40dB before stopping at almost 65dB before dropping to 30dB again.

shit ... wtf .. people can't live with this if they are hearing it .. I can't leave .. I have no idea what's going on or what this will cause health-wise. No idea if it will stop. over 24 hours non-stop so far.

I had ultrasound. As TI. Its 17khz and 20khz. One is a hum from a PC cpu fan. Other can't be explained. Low db
Nothing in the ultrasound. Just noise

Maybe a psyop of directed ultrasound. I stopped recording. They can point it at your Window or lift a roof tile and put a battery operated box under it lasting for weeks.

We have a electric tripwire for the roof entries now.

Thank for info. I may have to order a directional ultrasound detector. I've seen them under $200.

Thanks me too.

Thanks again for telling the truth.

I'm going to continue posting any changes regarding this ultrasound noise blanketing at least the immediate area around my property. I walked out into the street earlier and sound didn't really change much in intensity, except slightly louder outside, barely noticable.

This is just a complete mystery at this point. And even more so as time drags on. What next I wonder. There is something suspicious and sneaky going on around here.

There's some other things I noticed too this evening but unsure of until I notice it again. First time caught me off guard.

This sound has droned on for over a day now. I think my teeth with fillings in them are starting to hurt.

NNJ has the ringing too

What if ... ultrasound, maybe 5G, something harmonic .. activates dormant virus hiding within you, brings then all back to life?

NNJ?

This kind of concerns me because we have been told that this week and the next week will determine if we end up like NYC or not. And then this shit starts blasting like a mother#### in the neighborhood?

Excellent thread OP, and I will also say I hear the same frequency.

Thanks. I'm noticing more as time drags on. I notice my stomach is gurgling a LOT and my stomach muscles feel a little sore, cramped, as if I've done a bunch of situps. That happened last night too. I also felt as if I was slightly sunburned this morning, but that passed after a while.

That ultrasound will without a doubt make you sick if you're subjected to it long enough. And if like most people, you can't hear it and are unaware of it, you won't know what's going on with you. You might even think you're catching the flu. My eyes and sinuses were dripping last night, not that much though. This evening I feel dehydrated. Head still okay, no dizziness yet, but at times I think I feel a headache coming on but hasn't .. yet.

I have a few theories as to my experience with the ultrasound:

1) The U.S. Fed Government is communicating in a secret frequency for only top secret communication.

2) N.W.O. conspiracy for the use of cell phone towers to agitate the population via ultrasound to cause civil unrest.

3) My neighbors own a wireless communications company and are harassing me with ultrasound.

This seems like a lot of trouble to harass me. What what if I couldn't hear it, as can't many, maybe most people, that would have been wasted effort. And harass to what ends? None? Year after year?

Anyhow, I built a shelter for my cat and she finds relief in there and can sleep. It's a huge pile of thick blankets and walls of folded towels I bagged and lined around her space. Entry has turns. When she's in there, she doesn't seem bothered by any of this. Significant reduction in noise. She comes out to eat and say hi to me.

Venus sure looks bright to the West tonight.

Now I find myself wondering if that ultrasound can give you an aneurysm. To listen to that sound drone on you might think you're going to have one. But again, few can hear that high.

Status of this noise remains the same. My cat seems to think it is coming from the direction I think so too. She quickly looks that way if she notices a change in intensity too. And she looks upwards, towards the roof of this building near me. Latest overhead satellite photo shows some weird stuff recently installed on its roof and cables running to and for. That stuff wasn't there 3 years ago.

Okay, weird, at 11:11 PM here, the intensity of the ultrasound noise increased a bit, suddenly, maybe 5dB for a few seconds. I checked the detector and noticed alarm log indicated I heard correctly. Back to what it has been most all day. So .. does this mean someone is going to screw around again tonight? Now I hear variations again. What they getting ready to do? damn it, what is going on around here ..

So I think someone is fiddling around. I am hearing slight deviations in frequency and intensity that were not the same most of the day. It almost sounds like someone quickly cranked up a disk and turned it back down. This app is just giving me updated data every .5 or 1 second (or more - configurable) but my head is hearing the real live analog version of what's going on, so I hear those SLIDES when a dial is turned as opposed to a sudden sharp change when maybe a switch it flipped.

Getting cramps in the arches of my feet. May or may not be related, I am feeling dehydrated.

meant to say cranked up a dial, not disk, in above. Android changed it on me grrr

Thanks for being one of us. Keep us posted, I ran an app and can say its thankfully quiet right now.

So, it is approaching midnight. This is when weirdo stuff usually happens, after everyone around here goes to bed. I might be the only one up most nights, all night. After midnight is when things like all my wireless light would go on and off without my doing. They can be triggered wirelessly, using an infrared motion detector, and through the AC wiring (via other security devices). I had to remove all that stuff. Hacks began playing with it. What remains is one kitchen light switch which can be triggered with an IR sensor. I blinded that sensor and place it in different locations. My body can't trigger it this way. Yet, something pulses my home, maybe the neighborhood, and it triggers that blinded IR sensor which then turns on the kitchen light. And my motion detection lights in my back yard come on too. When I detect the pulses in the front of the house, it sets off all the same but in the front and the back. (stretches head .. wtf .. who is playing these games) Those same pulses cause my Amcrest security cameras to reboot. The pan/tilt take longer to reboot, the dome on comes right back up quickly. (stretches head .. wtf .. who is playing these games)

I notice this same stuff at other people's homes too. The neighbors front door light begins to strobe really fast, like the lightbulb is freaking out. And as quickly as it started, it stops.

I've seen a lot of weird stuff going on around here.

I have many dozens of other logged, recorded, data captures ... so many shenanigans going on around here for the last few years. And now this ultrasound crap .. in the middle of a supposed pandemic .. and .. (stretches head .. wtf .. who is playing these games)

.... ?? waiting for tonight's surprises ..
