It was a long time before I even realized I wasn't hearing the bird on a daily basis until I started realizing I was not able to understand what my grand kids were saying to me, thank goodness for bionic ears. Still have hearing problems because the bionic ear doesn't make my hearing as good as original, but it is sure better than it was. At least I can understand my grand kids better now, well, most of the time.
It is nice to hear even the noisy birds though.
Have a great day.
