I have a digital hearing aid. She checked it out pretty well, got all the wax out and changed a little filter I often forget to check. She also adjusted it using the computer to change the audio filtering to blank out more of the background noise and amplify the foreground a little.
This really did seem to help somewhat but it was decided that due to the length of time since the last one that I should get my hearing test updated. This requires a prescription from a doctor and so we scheduled another appointment.
Today I went in for the test. She did have to remove some wax from my ear. I then repeated all the words I could hear and pressed the button when I heard the various tones in the earphones. After this was all finished, she smiled and told me my high frequency hearing actually tested better than the last time.
I did not know you could actually improve. I thought you were sort of doomed to reduced capability as time goes by. My problems that I was concerned about were probably wax related in the ear and the hearing aid. Maybe the tuneup helped or maybe I really am better than before.
