Is that high pitched squealing or whistling noise that your hearing aid makes driving you crazy? I never realized how bad it was until one day when I was saying goodbye to my father. I was giving him a hug, and as I did so I told him that I loved him. The squealing noise that came out of his hearing aid made both of us jump! He told me that you get used to it, but I decided to investigate further to see if anything could be done.
