Is this a global phenomenon or localized sound?
I used to have pretty sensitive hearing and I have never heard this hum. Or maybe I have but didn't realize this hum was the supposed 'world hum'.
Hums I have heard have been like power lines vibrating in the wind, like a breath vibrates a reed in a wind instrument. Kind of like how a quiet alley
way can become a wailing banshee in the right wind conditions.
Heck even seen, or should I say heard the thin cords on a flag pole make 'hums' in a strong wind and there's even a sculpture about an hour from where
I live called the 'singing ship' that hums, moans and vibrates in the wind, a bit like a nature powered pipe organ.
Then you have things like metal pipes and such. Get the right pipe, heat up one end and it'll suck air through it and vibrate/howl as a result.
Thing is any 'odd' environmental noises I've heard I've usually been able to track it back to the cause.
Heck had a weird noise in my house for ages. Sounded like it was coming from the school up the road. Kind of a hum like a generator or something
running at a distance from me, I thought it might be a water pump on a large water tank they have over their.
Could of sworn it was external.
Turns out it was the ceiling fan in my bedroom. Just I guess due to the frequency and room acoustics it sounded like it was coming from the school. (I
was ready to march up their and tell them to turn off whatever was making the damn noise at night. lol)
Then we have to think about other things, like some people can hear a noise others can't due to the frequency their ears are capable of receiving.
This has been used as a weapon of sorts, with shopping malls playing supposedly annoying noises over their PA systems only 'youngsters' can hear, that
older people supposedly cannot in an attempt to drive away loitering teens.
Then again maybe that hum is in our heads? I often get high pitch whine in my ears, like the tones they play during a hearing test. They used to occur
more frequently as a kid and for longer, but generally only last a few seconds.
I guess that is what is called tinnitus, but it's not a ringing, it's a constant tone.
So yeah if there is a world wide hum, could be numerous reasons as to what it is. Could simply be wind rushing through a forest, or volcanic gases
passing through caverns or wind passing through massive power line towers or over various pipes chimneys and smoke stacks on houses and factories.
Could be a combination of many things. Could be them all. Could be local, could be global.
Only thing I am sure of is any hum will have a scientific cause behind it like it simply being the roar of the ocean that covers most of the Earth.
Sea's pretty noisy hey if you've ever been to a beach.
