A low hum in South Africa, Johannesburg
Low-frequency drone. Loudest at night, but present throughout the day. Keeps me awake at night and causes ear pain. I wear hearing aids with loss of hearing in the lower range. Seems to be where the hum is so my brain is picking up and converting to sound? It was really loud when I first heard it in 2013. I searched every night to find it, but no discernable source. I sold my house and moved about 10 km away. After a week i 'heard' again, but lower - only a few nights a week it keeps me awake now.

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…
