Hi Petra. Congratulations on correlating your ear tones with recent events :-) Speaking of tones, I have been having a few myself over the past few days. I hadn't been getting any for awhile but that seems to be changing. I suppose I should try to keep a log like you do to see if I can relate them to any events here locally. I have been having very high pitched tones that last for more than 15 seconds a pop today. These are different than normal because I normally will get one in one ear or it will start in one ear and then the other will join in at times. For the past two days they have been in stereo and very high pitched and long lasting. I have no idea if it means anything or not. I will just have to wait to see what transpires.
