Yes, it's still there. So I have three tinnitus sounds, but it's the high pitch in my left ear that is debilitating, the other ones I can mange with. But maybe it's also the combo of the hum and the high pitch that makes things feel like a laser is going through the head. Makes for a brain foggy sensation.
It's in the head. Not sure about the Hz but think mine could be at 100 Hz as well. I also think it feels like a vibration at times. My perception of the hum do vary; today when I woke up it felt really low. Good that people have it go away. I would definitely be able to handle it compared to the high pitch in my left ear which is likely due to inner ear damage. Every day is a struggle.
