I have a pair of 2 yr old Signia Styletto hearing aids. I am 88 years old.
Q1 - What are the names and descriptions to call different kinds of experienced sound distortion of voice? This is to help me to describe accurately what I hear when trying to understand peoples voices.
Q2 - How can I determine whether change in hearing experience over several years is due to my hearing aids or changes to my biology? Which is most prevalent in the population?
