it sounds like the engine of a car or a electric generator coming from the ground or another building around. The presence and intensity od the sound vary from very subtil to the impression I am myself vibrating. It's usually a continuous sound but it sometimes seems to "be played" with a pattern, like 3-4 seconds long and a 1/2 seond pause.

Earplugs make it worst as I feel the sound for internally and loudly.
