In general we do loose hearing in the upper end of the audio spectrum as we
age. Low frequency loss is usually due to certain type of ear illness,
usually the result of ear infections causing scaring of the ear drum and
subsequent rigidity. This can also cause certain narrow band or select
frequency loss more like a notch in the hearing spectrum
In the US most truck drivers and taxi drivers have more loss in the left ear
due to proximity to noise the result of driving with window down. In
countries in Europe that drive opposite the US, the loss is in the right
ear.

What "great information" are you refering to??
I thought we old farts lose hearing in higher range, not lower. Like
me, not hearing highs is great-you don't have to listen to the wife
as much anymore.(smile)

I was kind of surprised to see my original topic (which concerned
improvements to the Omni 6) turned into a discussion of hearing loss.
Like Ron, I thought aging generally resulted mostly in high frequency
loss. And Keith, I'm an OT also-- age 61, first licensed in 1959.
