It is cumulative. Each time, no real worry.

Over 20 years it just happens. I noticed one day when listening to some signals. Levels, at some frequencies were different.

Again, minor league. But, due to a few decades driving window down, it all did add up to a little something.

Overall in my life, apart from that window business, I have taken good care. The highs are rolling off some now. Normal.

Discrimination is still really good. But, I can now tell left ear from right.

Thanks for the tip. I will have to get a set.

So, you have to decide what is worth what.

At my peak, I could hear well through 22khz.

Today, I still hear very well, but range has dropped. 17khz or so.

I do not care much.

Discrimination, sensitivity related to things under 12khz is where all the good stuff is. Mostly normal aging. I have no worries. I can still often tell you who made a vintage watch by the sounds it makes.

Music is still great!

With a ton of work, I could have preserved more sensitivity, and a bit of range. But I have lived well too.

You must evaluate these things and act or not, now.

Hopefully, you have no worries aging up too.
