Hello,
I've recently noticed a, almost pure tone, 1.55kHz ringing in my right ear in rooms that have sound levels in the < 55-60 dB range. This frequency is really annoying! It is very noticeable with ear protection on.
A couple things I have noticed. Large stretches, arms reaching back over shoulders, make it much louder.
If I generate the ringing tone I can still hear the tone from the tone generator just fine but when I get the volume down near to or less than the level of the ringing I start to get this phase cancellation effect.
This is really annoying because in a room that has any 1.55kHz sound component to it and is low in volume, it creates this pulsating mosquito type sound.
Also I've noticed if I cover my ear and create the right amount of air pressure, it seems to go away, but then gets louder as I reduce the pressure back down. I've swept through frequencies on my computer and I don't really notice any hearing loss near there.
Thoughts on what to do?
