My hearing problems are similar to yours, Geezerette. Except mine started over 12 years ago when I was still working. I worked for a large foreign company which required that I attend periodic international phone call, meetings and some video conferences. I soon realized I was not understanding correctly some that was being said and some I just could not understand. I had my hearing checked and found I needed hearing aids. After doing research I decided on getting a pair of Phonak hearing aids. They were set up to specifically help my hearing problems which was different in each ear. I did not spend the extra money to get them linked together or have Bluetooth. But they still cost well over $4,000 total.
I had been warned that they would take time to get used to and they gave me a schedule of how much to wear them, increasing the time over two weeks. The first time I put them on and left the office I kept hearing strange noises. I thought it was something wrong with the hearing aids. Then when I got in my car to drive home, I immediately thought something was wrong with my car as I heard a funny sound, I did not recognize that sound, so I pulled over and opened the hood. Everything looked find so I started the engine and listened...no more sound. As soon as I started driving, I again heard that weird sound. I decided it was something with the hearing aids, again.
She I arrived home I called my ear doctor and told him I thought my new hearing aids were faulty. He assured me they were not! He explained that over the years as I had slowly lost hearing, that some sounds were lost, and my brain actually forgot what those sounds were. Then all of a sudden, bingo there is that sound, your brain tells you something new, but actually it is a sound you have forgotten. Within a few days all these mystery noises stopped, and I recognized them right away. These hearing aids have been wonderful and solved most all of my problems. I especially like what I was able to hear as my grandkids as babies learning to talk....glad I did not miss much of that...
I still use these same hearing aids although my hearing has gotten worse and they have adjusted them as best they can, time for some new ones, as I don't want to miss out...
By the way they were guaranteed for a year. Good thing, I forgot to take them off when I was getting an MRI on my head. They were ruined.
The company replaced them with no questions asked...
Good Luck
