I had this ringing in the ears.... was referred for hearing test and I have lost the ability to hear very high pitched noises (which is weird as I can seem to hear them in my ears!)
I am not even sure which ear it is coming from. Anyway, was fitted with hearing aids as I was borderline to get these fitted but I could not get on with them. Noises really made me jump and be extra nervous !!
I found that the noises whooshing, popping come and go, some days being more intense than others, but have learned to get on and live with it. I think if you accept it, the noise fades slightly. I find it worse in a room with no background noise. Also find that the noise gets louder if I get stressed about something, so I try relaxation CD's. Had an appointment with ENT specialist, found nothing. Found out that I had TMJ through teeth grinding at night. My mother had died and I put it down to anxiety levels increasing. Now, some days I notice it, other days I don't.
Hope this helps.
