    I just listened to the new video from Dr. MacPherson. From my experience, hypothesis #2 is out, because I cannot hear the hum in warmer months of the year. But I perceive it extremely well in the winter (and I realize my case is a bit different in this aspect). An internally generated sound like tinnitus, would not respond this way…I think.
    Last week a military jet made a landing at our local airport. When it took off, the rumble it created also manifested as a strong vibration. As many of us also “feel” the hum as a vibration, I got to wondering if the increased number of airplanes in the sky at all hours of the day and night may be the cause of the hum? Think about the droning rumble that a 747 makes when it passes overhead, then imagine the sound from 1000’s of them with the sound waves bouncing off the atmosphere and returning to earth as a combined, low frequency, droning sound. Many of us describe the hum as an “engine type sound and jet aircraft do indeed have a type of engine. Just thinking…

    “Global air traffic has increased 8 fold over the last 4 decades” (from: http://www.bitsofscience.org/graph-global-air-travel-increase-6848/ )

    • J.O. –

      It has been very plausibly suggested that the reason many hearers (myself included) “hear” the Hum significantly better in cold weather than in warm is because we tend the open windows in warm weather letting in environmental sound that masks (distracts from) the Hum. Aren’t you typical in this regard? Remember that sound levels are perceived logarithmically (in db).

      Further, you said “with the sound waves bouncing off the atmosphere and returning to earth.” Please expand on your contention. A few sound waves may be broadly bent back to earth (usually well below the levels planes fly) in certain instances, for a few minutes, but not generally. Most sound going up just goes up. There is no “top” of the atmosphere – it just peters out.

        Bernie, I’ve hear the hum each winter since 2016. It starts in Dec. and begins driving me nuts by Feb. where I can hear it 24/7 and even over background noise like the TV. I live in Colorado so nights don’t get warm enough to open the windows until late April early May. We had a very warm week for daytime highs in April and the hum got very faint. The next week was cooler and the hum was more pronounced and then pretty much gone by May. I’ve heard it only very slightly recently and have to focus on it to hear it.

        With the sound waves bouncing off the atmosphere comment, i was just hypothesizing and have no supportive evidence. I tossed that out there because when the hum is very strong, I believe i also “feel” it as a vibration and that jet taking off produced a vibration I could also feel.I was just trying to suggest a possible correlation as we have more and more planes in the skies at all times.
        Thanks for the question though, it’s valid I think and I have no expertise in sound waves or atmospheric science.

    It’s not #2. It’s external. It’s not #3 , no cumulative effect could “sum” in this way, ridiculous. It’s not #4, it’s two precise consistent frequencies. It’s the cell towers, or other 5G, military or alien related forces, perhaps intentional.
    It’s 146hz and 73 hz, period, which are a Perfect octave apart. It does go off for small periods of time, so It’s not quite 24/7. This also shows that it’s NOT 2, 3 or 4. To assume there’s not advanced technology being used in some secret way, is more than foolish. Do you think the deep state is going to tell you about it? If this is going to be understood, anyone serious is going to have to look where they “shouldn’t”, and may be stopped in the process, which will be quite telling. The Orwellian world is here and now.

    • I think the only thing you’ve written that I agree with is that 146 is a multiple of 73. As for the rest, I think there’s pretty powerful evidence that EM transmissions are not responsible. But, of course, if you have any solid evidence to offer, by all means post it here.

      • GS Handley says:

        I still find it stunningly unscientific to continue to NOT get specific about what hearers hear. I made that effort, and it’s being ridiculed,

        German researcher Harald Kautz-Vella has a few possible explanations, look up his lectures.

      • I’m not sure what you mean. What kind of specificity are you referring to? Are you familiar with the many posts on this topic found on this blog?

      • J.O. says:

        I can’t see where you’ve been ridiculed, but your statements do come off with lots of anger and are sort of accusatory. Hey, we’re just good peeps here trying to understand this phenomena. Dig?

    I respect the effort that went into building the World Hum Map, however, I’ve traveled extensively, and the hum is the same whether in central China, the Americas, Europe, or anywhere else. For hummers who travel, have you ever found a quiet place with no hum? I believe it simply has nothing to do with location – not the hum I hear. I’d be interested to know one thing: has a hummer ever gone into space? If so – and if they hear it – we can exclude all potential terrestrial sources for the hum.

    • J.O. says:

      It would be easier to go to the quiet room in Minneapolis. Potential astronauts admitting to hearing the hum would probably be scrubbed from the list.

    • I concluded several years ago that location does not matter (this is a fiercely debated point, however). I think the most convincing evidence for this is to overlay a population density map on top of the Hum Map, and you’ll see the striking correspondence between the two.
