You bring up a great point. I am one of the posters who has posted about a recent experience, a couple of days ago here in the south Denver metro
area. While I heard what I can only think to call "earthquake booms" here in CO during and hours after last year's quakes, and while those seemed
to come from the ground or even maybe the sky, these that I heard a couple or few days ago stopped me dead. It was at once mesmerizing and horrifying
at the same time, simply because I have never heard anything like that in my life. Some sounds that are new are still lovely, like the call of a rare
bird while on a tropical vacation. Though it hasn't been heard before, it is still lovely even if it is new. This was a new sound I've never heard
before and it was eerie, not because I haven't heard it before or have been conditioned to think it was kind of scary, it was indescribable. It was
attention-getting and I actually had goose bumps all over. If someone or some thing is knocking on the tank, it definitely works!
My other thought is, WHAT DOES IT MEAN or, better yet, what is it a sign of? I've heard and read all of the theories, i.e., meteor showers,
magnetism, solar flares, geologic processes, etc., but if this is the norm, why are we hearing it? Wouldn't we have heard it before? It's
definitely such a strange sound AND experience (my ears vibrated deep inside the whole time the low tones were being sounded and felt without hearing
any sound) that there's no way people are just now noticing this because it's in the news, media, youTube, etc., why now? That's the part that I
find scary, really. Intuitively, it seems like a harbinger of something on the horizon, whether natural or man-made.
I have a partial theory to add to the list of ones out there. I do not believe that whatever it is or whatever is causing it is something from space
or from a massive area underground. I believe these are small, localized events, which narrows down the list greatly. Just as many other experiences
seem local to a small neighborhood (yes, sometimes even whole towns hear them but that's not the norm), my husband and I heard it and my daughter
heard it 2/3 of a mile away. When I posted about this a couple days ago, other people in the general area in CO did not. I emailed contacts on my
town's site and it was forwarded to the police dept. I wanted to report the sound and wanted to see if anyone else had, too, and was told this
(names and identifying info edited out):
"Thank you for your report of this. I did check with dispatch and they do not have any other reports of sound disturbances. I will, however,
forward this to that department to check into it further. In the future, you may call their non-emergency number to report anything suspicious or out
of the ordinary. Their number is 303-***-****. Thank you and have a good weekend.
11/9/12 Emailed our Commanders for their input. ***** suggested asking ****** in Development Services. **** sent an email to ***** with this
11/9/12 Inquiries were made for noise complaints between 1300-1500 with none being found. **** Middle School was contacted, nothing found. Also, we
contacted Development Services regarding possible oil or gas drilling. There are no drilling permits applied for or approved by the state for any
drilling within Douglas County. If this noise is heard again, please contact our non-emergency number as soon as possible so we can send out a patrol
car to investigate. Their number is ***.***.****. Thank you."
So, first of all, can't believe they took this so seriously (I'm impressed), second of all, this means the sound was heard in a very, very limited
area, like a one mile radius. No one else called, but I didn't think to contact them either until yesterday, so people may not have reported it.
This being said, what can make that kind of sound in such a small area and remain invisible or without an identifiable source? My daughter heard it,
but she was out at recess and told us about it when she got home from school. My son, in the same school, did not hear it, but was in his classroom
at the time. I heard it as I was by my bathroom window, coming from outside, but my husband did not until he went outside once I heard it. All the
dogs in the neighborhood heard it, too. Strange.
