I was fitted with my hearing aids today. It was like someone turning on the light in a dark room. I went from dull mono to clean FM stereo. WOW! I could hear the door knobs tuning to open doors. I could hear my own footsteps! When I got home I heard this incessant knocking. Where was it coming from? I looked at the wall. It was the clock hanging in the living room! Now I can hear the dogs barking, sirens , neighbors, squirrels on the roof, cars and motorcycles on the road. I had gotten used to the muffled sound. I went outside and sat in my front yard. It is a pleasant day
