A low hum in Norway, Hamar

Very low frequence, humming, more often during Winter, short breaks and coming back after a few Seconds. Typical short break when I change posture. Not every day, more often evenings. I have been thinking a lot about this sound. Concluded after a long time of exploring it that it must be a variety of tinnitus because I thought I was the only one to hear this low frequent sound. This information raises an interesting question because it seems like many People can hear a sound like this.
