Low mechanical hum that is louder in-doors than outdoors. Worse when there is snow in the ground. My theory is that when I am stressed my tempanuc membrane becomes tighter and may pick it up. Or, I�m picking it up in my jaw. I have aspbergers and am sensitive to high frequency sounds and low hum but mid range conversation level sound can be hard for me to sort. I think it�s bed rock very very slowly slipping below the soil against other bedrock and it�s causing a hum like a violin bow over strings. Cathode tune noise used to really bother me as a kid, and I could/can still hear it when my ears are covered. I remember selling Boy Scout tickets door to door as a child and approaching a house I could tell if their tv was on. Sky noise does not bother me as much. If I camp at the bae of a mount Elbert in Chaffee county, Co I can sometimes hear the sky splitting around the peak as a low rumble like a jet far away that never gets closer or further. That noise is ok for me most of he time.
What they reported
First noticed: 2012
Pitch: 83 hz sine wave
Loudest: During the night
Where: Indoors
Symptoms: Headache, Insomnia, Nausea, Sense of vibration, Anxiety, I feel like I have to flee
Changes with weather: Louder in cold weather- seems to be louder when snow is on the ground. There is a transformer that sits on a cement pad about a half mile away near a retention pond. I thought that maybe the water in the ground and snow helps conduct the hum. But I�ve not been able to verify it. When I put my hands on the enclosure I can feel a low cycle vibration but I can hear anything unless I rest my jaw on it and it�s not the same that I hear at my house. I�ve turned off the power to my house at the breaker box and I still can pick it up. I�ve heard a hum camping several times- this has occurred elsewhere and I can�t figure it out.

Has this happened to you?
Write it down while you still remember the details. We will look for the others.
If this reminds you of something a friend or a relative told you once and never mentioned again, send them this page. Reading that a stranger described the same thing is usually the part that helps.
Nothing is tracked back to you and nothing is sent on your behalf. The link is just the page you are reading.
