It was too early in the morning for me to call it. (I would have to use Skype). But the one thing I wish I could have mentioned to the doctor was that there are many places in Europe who hear this two, and if you understand physics.... grasp this.
A heterodyne is form when two, or more frequencies are mixed together with one slightly off pitch from the other. So in simple terms if you have a 1,000 hz tone, and then a 1,020 hz tone, the resulting heterodyne will be the difference, or 20 hz. You would not really hear the beat/tone because of the amplitude of the primary frequencies.
So let's suppose the primary frequencies are higher, and instead of being generated by a tone generator, they are made by the wind blowing through a land area. Such as THIS wind noise. If there was a second wind noise which was +/- 20 hz of the first noise, then the result would be that low rumble or hum. Next to the lake (in the video) you would hear the wind and the hum, but at a distance of a mile or more you might not hear the wind but just the heterodyne because low frequencies carry further than high frequencies, especially in urban areas.
So let's take this one step more since we can hear the wind in the example I provided. Suppose the primary sounds were in excess of 25,000 hz, which is above human hearing. And again we have a sounds which are 25,000 hz and 25,020 hz. The result would be that low hum with no trace of the primary tones.
The primary tones could also be two of the military transmitters as well. For example, what two ELF transmitters were heard at the same intensity at the same time. Let's take the first two in the list, one in India at 16,300 hz and the one in Norway on 16,400 hz. If they were detected at the same level they would produce a 100 hz heterodyne.
I don't buy the drilling machine theory as machines, (if you have ever been around machine which bore through earth, do not exhibit a hum. They are literally grinding rock which makes all sorts of noise. However, I might buy the fact that a slow movement of the earth's crust could produce something like the buzz as it "chatters". I'm more inclined to believe it's atmospheric since there are KNOWN phenomenon which produces sound, including sprites and whistlers.
