I happen to be lucky enough to have my niece as my audiologist. I trust her and I think she takes good care of me. My two cents is this, if you don’t buy your hearing aids from someone who can adjust the prescription to your specific needs, you’re probably over treating or under treating your problem. My hearing aids, both left and right, are adjusted to treat and amplify only my deficiencies on that ear. Everything else goes right by the holes in the piece in my ear and on to my ear drum. Hearing aids are expensive. You want a set that can be adjusted as your prescription changes. My hearing is checked annually and if adjustments are needed, they are made. Looking at the computer monitor my niece works from you think you’re looking at a graphic equalizer. This is very familiar stuff to all of us if you think about it. All of this is done in the digital realm. Gone are the days of big, bulky, analog hearing aids like my mom used to wear.
Something to ponder: do digital or analog hearing aids sound better? Wow! What a can of worms that could be. To my knowledge, none of them are analog anymore. Still, it’s fun to think about. Next thing you know I’ll have little tubes glowing next to my ears and a battery life of about 1 hour.
