I don't know what you said

I think the main stressor in our house is my weakening hearing.  I can usually detect that somebody is speaking.  My problem is decoding, comprehension.  If a comment is delivered in a very high voice or spoken very quickly, I have less chance of comprehending what was said.  The voice tone, the accompanying facial expression help but I often have to admit “I don’t know what you said.” I asked my hearing doctor about the problem and she said that the part of my brain that understands spoken words is wearing out. So far, I have not gotten too interested in a cochlear implant.
