Hi,
Does anyone know what would cause these frequencies to show on spectroid app? Non stop, 24/7 pulsed emitter type sound, high pitched. Area: kitchen at night. It travels all around the kitchen.at different points. Fast flickering. It's a video screenshot as can't upload video.Screenshot_20250602_201152_Gallery.jpg
Thank you!

It's all very audible to me. I can hear this all super clearly, high pitched and the graph shows that the constant fluctuations of pulsed sound exists (no one else seems to be able to hear it).
Turn off the breakers, one by one, until the source is found. Then It's up to you to decide what to do. Most of us old guys hear all sorts of whines, and high pitched sounds. I find that playing soft music I like reduces that noise in the ear and head.

Jazz on the JVC works for me.

Did try turning off the whole electric, it does not go. Will try your suggestion. Maybe the source has its own generator...
Using am radio can find lots of points of interference when electric is completely off. Thank you for the soft music suggestions :D:cool:
Electrical energy is everywhere today, the source is the modern, electrical energy slave using planet we live on. The levels you see are in the micro-watt or less range. It's up to you to decide what to do, personally I've been in a lot a worse than nano-watt energy fields for most of my life. Chocolate cake is far more dangerous.

It is part of the CIA mind control program. What have you done to make you a target?

But, seriously,

Analysed some of the sounds in a music audio app and was able to clean it up. It brought out some very interesting audio embedded within short recordings of what some would say are just pulsed bursts of energy or silent sound. Directional speakers etc can also create this type...
Please share a recording, but DO NOT tell us what you are hearing, let us evaluate it ourselves.

Edited to add: Both before and after your manipulation.

The one "mysterious noise" problem that I solved for a friend in the past was quite interesting. It was everywhere, and quite loud, and scaring her cats terribly. I tried all the breakers and then the main breaker, all with no effect. Eventually I tracked it down to the furnace, and the humidifier. The float valve was delivering a steady "water hammer" oscillation. Somehow oscillating like a water-powered whistle. turning the fill valve mostly off stopped it. Turning the fill valve back to full started it, repeatedly.
So the oscillation noise could be the water valve on the refrigerator's ice maker. Or on the heating system humidifier. Or the one on the water filtration system, doing it's evening regeneration process.
So there are some likely suspects for the sound that ids hard to locate because it is generated as a vibration of a radiating surface, not as a point source.

Hi!

Thank you so much for your reply and all the detail. It means a lot. I did try to record the audio but energy shows more visually on graphs than if someone were to listen back to the recording.

When AM radio is anywhere near the boiler and thermostat receiver on wall, there's a steady high pitched beep, and another 2nd beep intermittently, in between the beat of the steady one, same type of pitch (which echoes right through the ceiling upstairs). This can only be heard when the radio is near boiler.
When boiler is turned off by the switch that aspect and steady alarm goes away. Not sure whether it is linked to this but possibly. Boiler was serviced nothing strange found and they advised that it's probably just because thermostats and receivers work on RF.

I am new to all of this and just trying to locate source/s but it reverberates throughout each room. Know I need recordings will try that again.

If I never find out for sure at least I learned some things along the way...:)


What you described definitely does sound so like what it could be and you described it all so precisely.

Thank you very much. :):cool:

Oh Wow!! If there is a signal picked up in an AM radio, then at least part of the operation is electrical. BUT that could be a high harmonic content PWM voltage, or some magnetic device, such as a solenoid valve, or relay, acting as an audio transducer. OR even a PWM controlled variable speed motor. AND, the possibility of an oscillating check valve also exists, although tat producing an RF noise signal is a stretch.
If there are wires on screw terminals, checking all of the terminals for adequate tightness may be in order. I once fixed a problem that had others puzzled simply by tightening one terminal of a 3-phase motor. (strange but true)

The AM radio is receiving in the .5-1MHz range, impossible to detect aurally. The display show energy in the ~50-250Hz range, potentially audible but nothing that would be described as "high pitched".

I think you are chasing a phantom. Have you considered the possibility of tinnitus or other endemic origin?

Look at the text I quoted in post #8. The post it was quoted from has apparently been deleted, I wish I had quoted it in its entirety. It also revealed that no one else can hear these “sounds”, and implied that they contained messages revealed by his post processing.

Deleting that post is enough to convince me he a either a troll or mentally ill.

I suspect this is the same person posted pretty much the same nonsense a couple of years ago and was eventually banned.

Yes, I don't think it's a troll. Unfortunately people with issues are targeted with EM signal BS to sell them gear or to spend money for various cures.

It's a common grift, that sadly can cause fear in people to the point the mind generates a phantom world to justify that fear.

More sad than troll.

The test to determine if a sound that one person is hearing is the result of tinnitus or a similar affliction is both easy and simple: Just block all external sounds from the individuals ears, and if there is no change in the perceived sound, then it is internal. If it ceases, then it is externally produced. The ear blocking can be as simple as fingers stopping one's ears.

Of course there is also the case of others denying the existence of some sound, either because they have a hearing loss, or just out of nastiness. But a sound level may be verified thru observation of a volume level indicator on a recording device, when covering the microphone reduces the level indication.

The unfortunate reality of some forms of tinnitus is that is indeed real. Imagine hearing a tone, about 7.3 kHz, about 80dB, constantly. 24/7 365!
Would that affect the sanity of some folks?? Would it have any effect at all??

I suffer from tinnitus. Mine must be very mild, because I do not notice it most of the time. But as soon as I read you post, I could hear the constant high frequency sound.

I am also afflicted, and mine is not mild. Somehow I can ignore it, amazing to those who claim it would drive them insane. Possibly it has led me to ignore a lot of unpleasantness over the years. It has also lead to my thinking that boxing another's ears should be classed as a capital crime.
