A low hum in United States, Mt. Healthy
It sounds like the background hum from a device like a furnace or dehumidifier. It stays at a constant volume and has a regular oscillation wave pattern. Often, when I lay down to sleep, I hear what sounds like a radio tuned to a talk show in an adjoining room. It's as if I can almost make out words, but not quite. The sound is on the very edge of my perception.

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 dist…
