A low hum in USA, Denison

A bass sound like machinery drilling underground, usually begins approximately at 2:00am. The sound is intermittent or will continue for 7-10 seconds before becoming an on/off sound. The sound became noticeable in the daytime when sub-freezing temperatures and snow fell upon Texas 02.09. - 02.18.21. Usually have ambient sounds, but when electricity diminished, the sound was audible and had the same constant & intermittent rhythm. This motivated me to search for the sound on the internet and discovered it is called The Hum. Have been hearing this sound for a few years since we moved here. Did not experience this sound living in Dallas, Texas or Florida or New York. Glad to find I'm not the only one. Found out about The Hum on the internet recently. Continues to be mysterious, not sure if there is not some type of underground cavern living space being developed...

Low frequency hum, always same frequency, I'd estimate around 50hz (at least my perception). I only hear it at/in my home, if I'm at another location, I don't think I've ever heard of it.
