A low hum in usa, clovis
heavy equipment motor sound outside my home. I can fell the vibrations along with the sound, especially when on the ground level of my home, concrete slab/tile~ floor, sitting and barefoot or socks on feet during the quiet late evening. sometimes during the week mid-day which is always a less quieter deep vib tone somewhat faint but there and nothing upstairs period. when I lay down to sleep upstairs and sleep on my sides, the hum is loud. My wife does not hear it as much as I do and my wife and I do ground ourselves barefoot in our grass backyard a few times a week...
