Hi I got new hearing aids about 2 years ago and when I recently had a test for vocabulary understanding without the aids, it was way down. Has anyone experienced this? I have a high frequency deafness and the aids were purchased through a vocational rehab program since I work. I have since discontinued the audiologist because she simply did not listen to me when I told her what kind of ear molds I wanted. I wound up paying for my own at a nice high cost. I wanted air holes in the molds and the soft molds were not comfortable for me. My aids are over the ear ones. I have used hearing aids for quite a few decades now.
