"Normal range" == normal for a city dweller of your age who has worked as a
blacksmith, it is an insurers defintion. Normal would imply that you had
less than 20 dB threshold shift from 20 Hz to quite possibly 32 kHz. This
based on some wording in some newspaper article about the results of
audiology on jungle tribes in Africa that I recall reading 30+ years ago.
"Normal range" just means that you don't have a valid insurance claim.

There is no good reason I am aware of - but I am unskilled - to assume that
age related hearing loss is anything but simple noise damage.
