Low and deep sounding vibration that is consistent and pulsing. At first I thought it was generated by an appliance in my house. But I shut off all appliances. Then I shut the power to my house. Then I thought it was the water line coming to my house so I shut it off at the box. I realized I was able to hear it outside as well. It was more pronounced under my carport, but was still audible in the open air.

It's a low frequency pulsating droning/rumbling similar to the sound a heat/water pump (HVAC) or a diesel generator makes. I live about 800meters (half a mile) from the largest Navel base in…

Low pitch hum When I first heard it in my house I searched all over the house for it. I swore it was electrical. It reminded me of a motor that was stopped but still had power to it. That ni…
the accounts read alike, found by meaning rather than by shared details
Write it down while you still remember the details. We will look for the others.
Tell us what you sawIf 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.
