An endless, distant low rumbling like the sound of a truck engine, but much quieter. It�s not terrifyingly loud but I can�t help but notice it. When I�m focused on something,

Low, constant, almost pulsing hum�like that of the background engine noise of the Enterprise on Star Trek: TNG or the 'glowing' hum of the nuclear reactor on the Simpson's; a little rap
