This is a post in followup to Kathleen Kesner's recent post on "buzzing".

As a preface, I have no problems with my ears, I am a very stable person and I would normally not write of such things however.......

I have been hearing? (for lack of a better word) a pulsing hum for several years.  It overlays the high pitched ringing which is pretty much constant these days.  However, around 2/18-2/19 it became really intense and contained 3 distinct tones.  The normal high pitch ring, the pulsing hum and an almost morse code like, louder tone on top of the 2 subtler sounds.

I have somewhat become accustomed to the ringing and pulsing hum sounds but on those 2 days I just about could not bear it.  The hum was relentless and I felt like my skull was vibrating.  The morse code sound did not last long ... perhaps and hour but it was so "loud" I could barely focus on anything else.  It was so distinct and clear I almost grabbed a pen to document the "morse code" sounds.

The pulsing hum was rather disturbing when it started a few years ago but I have gotten used to it.  I almost hate to say so but it also appears to be interactive.  There are days I do not hear it and almost miss it and I have realized that if I mimic (hum with my voice) the precise tone it begins or "responds" to me and begins pulsing.  Alternatively, on days where it is really intense and when I suddenly realize I have not "acknowledged" it that day, if I repeat the tone back it "calms down" and I can continue with my day.  It does not go away but seems to "relax" because I call out to it.  I've gotten used to just acknowledging the tone first thing in the morning so it doesn't "freak out" on me.  It's quite strange.

After the 19th, the tones calmed down to their normal activity and the "morse code" tone has not returned as of yet.
