A low hum in Santa Clara County, San Jose 95129

Very low frequency, has changed over the years from a steadier sound to "pulsing" and louder. I believe it is resonating the walls of the (enclosure) house. It can be heard better inside an enclosure. It wasn't loud enough to be heard in a vehicle until after the day it stopped, then came back with a vengeance. I used a car stethoscope to listen and I can hear it on the house walls, trees, the ground outside.
