Underground vibration - low frequency hum
or some time now, i have noticed a low hum/vibrating noise, particularly noticeable during the night when there is little other noise. It's continual and sounds as though something is running, like an electrical appliance. Have had all checked out and not internal noise. A lot of people in the Acton Area have also noticed this. Anyone else?
