A low hum in Germany, Teltow

Constant low frequency humming sound with split second breaks in between. I can feel a vibration as well as hear the sound. I thought it was a truck outside but it did not stop. I had never heard about this. I went to Google bc I thought something was happening to “the world”. It sounds like it’s coming from the universe. And then I searched for a place to report it as this is not normal.
