Low frequency hum started like a welder going on and off. Eventually it became constant low frequency. Noticrable more of a night in bed than day, but can be heard in quiet environments. In bed, if I lay very still and stop breathing, the hum has stopped at times. I suspected another SCDS hole in my left ear, but this was not diagnosed by a CT scan. A Story about the 'Hum' on ABC online Australia jumped out at me !

A low, continuous hum I first noticed the hum when I moved into my flat in 1999. It was extremely loud and intermittent - it would hum for a few seconds, stop for a few seconds, start again.…
