A low hum in Wa State, California

I have heard a low hum like the A/C or Heat Pump running for decades. I can hear it generally all the time , some times more than others, def very clearly at night and in bed. I have lived across the country and have heard it in every place. I have been traveling to Italy in the last 6 years and hear it there as well. Thank you for doing this. I have 30 years highest level corporate data management and display. If you need any help hit me up for a resume and I would love to help.

What they reported

First noticed: Before 1990

Pitch: 30 hz typically 25 hz all the time.

Loudest: During the night

Where: Equal indoors and outdoors

Changes with weather: No and for the last answer I have lived under a bridge, in a box in the woods, and in shitty houses and some of the finest and the hum is the same.

What stood out: a low hum
