I would like to add my thoughts and experiences here if i may.
I have read posts on other sites where some people only hear some types of these sounds inside the home.
I am one of those persons who only hear the low deisel engine sound within the home and not all over the house either, but in some spots.
I am a housewife and i was a mom for years and yes at times the home was noisy but my son was grown when we first began to hear this in florida.
we experimented by turning off all equipment in the house first. we tried this on a sunny, calm day when weather was ok . it still cound be felt and
heard by us.
we heard it at night too . i personally can hear it turn on, start up, vibrate at various frequencys and then shut off abruptly. i have wondered if
it was harp, earthquake forerunners, and many other theorys but i have never heard it outside. my son and i often went outside and laid ears to the
ground but heard nothing until we returned inside and then i select spots in the home we heard and felt the vibration. this was back in the 1990s
we moved and did at times experience it again . now its increasing in sc where we live .
several times through the years we have heard stomping and shaking sounds in several homes we lived in a long time ago.
i just wanted to say that some types of sounds by some people are only heard inside the house.
i have not heard the other sounds like these videos depict as yet but i agree those would be i feel heard outside too as well as within a building. i
just wanted to clarify this. sincerely invisiblegirl
