Hi Teresa,

Thanks for taking the time to reply. I am 67 and overall in good health. The only medication I take is 0.5mg Lisinopril for blood pressure control, and have been on that for many years with no ill effects. As far as I know, there is no history of this type of hearing loss in my family. I have several brothers in my same general age range, and they don’t have any issues.

When I first started having the low-frequency loss problem, I had a hearing test from an audiologist. The results were considered normal for my age -- just a moderate loss of high frequencies in both ears. If there's anything specific from the results you'd like to know, I'll gladly share them. I have the full report here.

The ENT looked in my ears with some type of large machine -- sorry to say I don't know what it's called. He said everything looked "perfect." He also performed a test using a tuning fork placed at various locations around my head. Again, no problems noted. He also performed a test where he had me lean back and checked for unusual activity in my eyes.

Right now I'm really concerned about this odd "pitch-shifting" effect I'm hearing on voices. It's kind of like voices are partially going through a hollow tube. I even hear it on my own voice, which is quite odd. I emailed the ENT about this earlier today, but have not yet received a reply.

That's the weirdest thing about all this -- it just keeps evolving. Never seems to be the same two days in a row.

Well, thanks again for your help -- it is appreciated!
