A low hum in USA, Rohnert Park
A low frequency hum, accompanied with a higher sound. I could probably find both sounds on a keyboard. Sometimes it sputters. Every once in a while, the sound disappears and I find relief for a day or two. But then it is back. I hear it when I come home from work, in my car. But not outside. It�s very loud in my house. Also, I�ve heard it everywhere I visit and sleep � Berkeley, Utah, all over Ireland. Everywhere. It started about 7 years ago. My neighbor heard it too, the moment it started. She says she plays music in her living room to drown out the hum.

It's a hum, a vibration, a low frequency sound. I hear it mostly at night, but also some days, it sounds cyclical, like peaks and valleys in the sound, like rolling, constant, annoying. I st…
