No, I don't think so. I have 3 or 4 different sounds going on. Not very loud, thank goodness! Mostly low pitched hums. There is one that is two notes, a major second apart (the pitch, I mean) and it pauses on the low, but ALWAYS ends on the higher note.Is that what it means? Wow, my brain must be plumb worn out by now then. I REALLY hate it when the base level tinnitus jumps an octave and goes to about 100 dB.
