Low pulsating hum This is my second submission. I put 29631 but we are closer to Central SC 29630. Today's sound is more pulsating. (Meaning... low hum then a really intense louder hum then back down to a lower hum) It's definitely electrical. I actually went outside to see if I could hear it and had a family member come to. This was about 5:45 am. We both heard it. Normally, I have heard it around 11 pm to 3 am. We live 2 /12 miles from big transformers and 10 miles from nuclear plant. They think it could be city lights or someone's heating unit fan. But it seems so bizarre that the sound can be heard indoors as well. Air is carrying the sound. We do have food stores within walking distance. And it's not the sound of the train that comes through. It heavily rained yesterday. Ground is wet today 12/22/18. Hope this info helps. Thanks.

Write it down while you still remember the details. We will look for the others.
