I went to a well known hearing aid company and got a thorough test covering frequencies in each ear and also word recognition evaluation for each ear. I was surprised how many I missed particularly with "sh" and "ch" or containing "s" sounds.
My insurance and the VA covered about half of the costs and I shelled out about $3K for two. They run on rechargeable batteries, connect to my phone and some devices with bluetooth. They are programmable using my phone. I can adjust frequency and directional sensitivities.
I realize how valuable they are when I forget to wear them. There really is a big difference for me.
you know my husband did active duty and then joined the Guard...his pension is nothing like regular military but the savings in prescription costs and hearing aides is worth a ton to us...
