All of the above, plus one. High pitched sound - EBS is about right. Mute button doesn't work
. Sometimes I suddenly get a very loud pulsing, about 3 or 4 short bursts. It actually makes me jump! The most aggrevating thing is that every sound that comes in my good ear is echoed as louder tinnitus in my deaf ear. If I scratch the side of my face (good side), I get loud but muffled scratching noise tinnitus! It is way strange. So in a room with lots of equipment, I get a deafening roar (well, I'm already deaf, so maybe that's not a good description now
) in the deaf ear.
I only had the EBS pre-surgery. Everything else is value added, and they did not charge me extra for it.
I also have a new noise in my good ear. Depending on how my head is positioned, I get what sounds like a stead clicking or dripping noise. Very loud, and you can almost feel it too. It's definitely related to pulse, because it always stays in perfect rhythm with my heartbeat. Click-Click-Click-Click-Click...KABOOM!
Ok, no kaboom.
