A low hum in South Australia 5211
It's similar to the sound of my fridge when the motor cuts in, only a bit lower in frequency. I can also compare it to the distant, low sound of an engine running or a cement mixer on a distant building site. It's a continual hum with no change in tone which seems to be louder when there's no other sound e.g. at night when trying to sleep, it keeps me awake.
It's similar to the noise I hear when I block my ears with my fingers but not quite as loud.
