Now, I would like to add a little twist here:
A couple of weeks ago I had a nice little ringing tinnitus in my right
ear. (Luckily it went away after a week, just when I started to get
worried about going crazy).
So, I observed that the loudness of my "built-in-sine-wave" increased when
yawning (no change in pitch, however). My physician said the the cause
of tinnitus is usually some inner ear or auditory nerve injury. If so,
how could the loudness be altered by a middle-ear "operation" (yawning)?
Or maybe yawning made all the other background sounds softer and thus
tinnitus seemed to get louder?
