I'm an older man and have one issue that I am looking for information on. My hearing was recently diagnosed with hearing loss, especially of the higher frequencies. I was told that my hearing test indicated nerve hearing loss common for my age. I had gotten a CAT scan looking for other issues.
If I pressurize my ears (Valsalva Maneuver, I believe) there is a great but brief improvement in my higher frequency response. I was seeing an ear specialist and asked him about it. There was no available information.
I find that hearing the high frequency sound response improve so strongly from simply pressurizing my ears does not seem consistent with 'nerve hearing loss'.
I have tried searching and get nowhere. I noted that the carotid artery passes next to my ear and that the Valsalva Maneuver has some complex effects on blood pressure. What is known about this?
If you have any information that might apply please post.
