heh I think ive experienced this at least twice in my lifetime.
In my original city of birth, Auckland, every few decades we'd get this 'Hum' turn up it was even mentioned on the news the last time it was
noticed in 98 maybe 99? and it was mentioned to have turned up at a similar time quite a few years earlier. I doubt id be able to recognize it these
days since like most people I have some level of tinnitus and its worse than what it used to be as a teenager. Only some people can hear it, and it
effected some worse than others some even mentioned it made it hard to sleep, I never had it like that but I could hear/feel the 'hum' quite
easily.
But for me the hum when it turned up twice in those 20-23 years in Auckland was basically as i could describe it like a fridge motor running just out
of perception range ie you can juuust make it out but cant tell if its you or something external (and it was not tinnitus which has a completely
different sound to it, which is more like a cricket stuck in mid tone). Its more like you felt the 'hum' rather than heard it. Unless youve
heard/felt it you cant really understand what its like which sort of makes skeptics go 'umm yeah right'.
The thing was the 'hum' was for me louder outside than it was inside and it was exactly the same pitch and feeling to it regardless of where you
where, along with being completely unable to pin point in terms of direction. Basically it was like it was everywhere at once. It also only lasted
about a month or so both times I experienced it.
Where I live now I have not heard it in the last 8-9 years. Could be from living in a large city while I now live in a small town, but considering it
appeared cyclic over many years of not being present usually linked to a season (summer) and omni present who knows what it is/was. If it had been
industrial you'd think it would always be around.
Am I sensitive, no idea, my mum could hear it but the rest of the family couldnt. Of note there was a UFO doco aired on TV here during the late 90's
that had a story about some corp circle audio recordings of a strange hum that was mentioned to make some people nauseated when heard... they played
the audio tape the researchers had gathered from the site and played it, when they did I got a short wave of nausea so maybe im sensitive to those
sorts of things.
The 'hum' exists... but what it is I have no idea.
Edit:- Ah looks like I was out by about 2 years
but heres a link to the 'Hum' I experienced.
Auckland Mystery Hum
A bit odd they mentioned its louder inside than out since for me it was louder out than in, although could be just poor recollection on my part (being
15 years ago and all
). Also doesnt seem to mention the fact its popped up before, which it has.
