Low frequency pulsating late at night when everything is quiet. Specifically elevated when then there is no wind. The quieter the evening, the louder the hum. Its almost like a hovering or faint generator sound. There are no factories, power stations or sub stations within a 10km radius from my home Ask what is the spacing of the rhythm in seconds or milliseconds and how long the the duration is per session. Most nights it starts around midnight and carries on until 4 am.

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 hum-…
