very low rumbling or hum/vibration. sometimes it sounds like another "whatever" starts humming at the same time. It kind of doubles in intensity briefly. When I heard it a number of years ago, it was for a short time - maybe a few days. But I could feel the house vibrate or shake a little at times. So far now in 2018 - no shaking.
