Long low sine wave form. 24-30Hertz I will say that trying to use ear plugs or noise cancelling headphones doesn’t seem to work. They actually almost make it the hum more pronounced. Durni…

Low rumbling hum. Like machinery off in the distance. I can "feel-hear" it. So when you ask if it's in both ears, that's almost difficult to answer. It's just "there" ... kind of always …
