Rumbling in Skagit County, WA on 1/6/2015 at about 10:50 AM
I have started a couple of other epic threads here on ATS in the past, and I haven't been around much lately, but I'm excited about this one. Why?
Because I FINALLY captured, in all its glory, what has been haunting me now for several years. I say haunting, because it's kind of a scary thing to
experience, but almost impossible to record, due to the low frequency. You FEEL it as much as hear it.
However, I recently purchased a professional recording mic with built-in sound board so I could narrate and produce my own audiobooks. So, not only is
it a great mic, but it works by hooking up to my laptop and using the audacity software. Meaning...it's portable. So, today when the rumbling started
up and it was REALLY loud, I grabbed my stuff and went out in the driveway. I sat the mic (on its tripod stand) on my cement driveway to capture
And WOW...did it ever capture it!!!!
This part is EXTREMELY important. ***DO NOT TRY TO LISTEN TO THIS WITHOUT QUALITY EARPHONES*** Because it won't work. Trust me. If you respond to this
OP with: "There's nothing there!", then we know you didn't read this. It really is there and it is VERY loud, but it's a waste of your time if your
speakers don't register the lower decibels. I can't hear it over my lap top speakers, hardly on my cheap earbuds, but its almost defening with my
professional Sony, MDR's.
What is this noise? No one knows. The most popular speculation from my family and friends (yes, they hear it too. It's not just in my head.
that it's coming from the NAS Whidbey Base (Naval base). A couple of years ago, they began a program where they test engines out on the deck. They are
very loud, I guess. My problem with this, however, is that my house is 30 miles NE of the base, and I know someone over 60 miles to the East that
heard it one particular night when it was really loud. Today, I would believe that if I were ON the base...but not 30 miles from it. (and I've been
hearing it for nearly 8 years now)
I have always thought it geological in nature. WHY? Because I have experienced two large quakes. A 6.1 in California and the 6.7 Nisqually quake right
here in Skagit County. This is what it sounds like: that low rumble that builds in intensity until the shaking starts. Only, right when you think the
shaking is going to start: it cuts out abruptly. So...I am clueless.
I would LOVE some help in determining what sort of sound this is. I have no doubt it is a sound wave. It registered a couple of different times on a
special seismometer out in that area as a sound wave.

to listen to the sound. it starts out with the rumble and it drops off at :39 seconds. A
helicopter then flies directly overhead and the rumbling starts again at 1:24, literally drowning out the helicopter. There are birds chirping, a
couple of cars go by, you can hear a train in the distance at one point...these are all totally and completely drowned out by this rumble.
(this is an MP3 file that is totally unedited or mastered. I left the entire recording intact for integrity)
Using my audacity program, I ran a couple of passes to highlight the frequencies:
Here is a map showing where I took the recording, in relation to the Naval Base:
So what say you, ATS? Any ideas, thoughts, speculations? Anyone interested in the RAW audacity file so you can deconstruct it and nail down the freq?
(I have a message in to TA)
