Hum the buzz that drives the world crazy

The topic is interesting, but for the moment I won't comment on it because I risk writing a poem.

I am not joking, there are various factors that contribute to making the whole thing interesting.

...could it be Schumann's pathology?

.....well I don't know what it is but it can be heard at my house too, as if there were something electrical "sizzling" and others hear it too. I also unplugged everything from the sockets... but it sounds the same. It's just not as intense as described in the article!! It must be the sound of silence!!!

I venture a hypothesis, could it be some form of electroacoustic pollution? perhaps the electrical system lacks shielding.

I read the article you posted but there are several contradictions. It makes me think that perhaps the source is not very authoritative. That it is perceived more during the night hours seems obvious to me... There aren't all the noises of the day and therefore it is easier to listen to. That it increases in volume at night seems absurd to me, also because by smell I believe they are electromagnetic in nature. I remember that my ex-girlfriend, who lived near the Radio Maria antennas, on certain days and with particular weather conditions, could hear the radio from the radiator. The thing is quite strange but I don't think she was telling me falsehoods. For this reason, I think the noise is certainly attributable to electromagnetic waves and the best thing in these cases would be, first of all, to make sure that the amount of electromagnetic waves in your home is below the maximum allowed limit and to understand what the frequency of the electromagnetic field you are exposed to is. For extremely low-frequency waves, there are no studies demonstrating their safety for health; for electromagnetic fields induced by common use frequencies (50/60 Hz), the maximum exposure limit is 100 micro-Tesla, 10 micro-Tesla for 4 hours of exposure, and 3 micro-Tesla ideal inside homes. Instead of you, first of all, I would try to understand, with a field meter, what type of electromagnetic radiation you are subjected to and at what power; from there, one tries to proceed by exclusion.

The ear being able to perceive something below 20 Hz is absolutely impossible due to physical limits imposed by the anatomy of the human ear. It would be necessary to understand if the signal presents harmonics; in this case, you could hear those, but until you perform a measurement, you will never be able to understand what might be causing this problem.

I had also thought of those because we have mobile phone antennas right in front of us, but I didn't think they made noise! They are in the building on the other side of the street, and is this humming not present outside, or is it covered by external noise? Giovanni, do you have them?

I have an electromagnetic wave meter and it detects out-of-range peaks at certain times of the day near the windows and behind exposed walls, so much so that to protect the children we had ARPA come to perform surveys and they said the average was within legal limits... but out of fear, we still put up curtains with shielding fabric. ..what surprises me is that it can be heard more in one particular room and it is the one least exposed to these antennas...the electrical system is shielded!

There are no repeaters or high-voltage poles nearby; I practically live in the countryside, so I would rule out "intrusions" from the outside. I am becoming increasingly convinced that it is an internal problem within the house.

It would be us Sardinians... to have a bionic ear!!!!!!! but my husband is Sicilian..!

Even my cat can't hear much
