[K3] One Last Hearing Story

[Edward R Cole]

Very interesting story!  I recall Rick's R2 (I think it was called)
which was an analog precursor to the SDR of today.

I think the lesson is well put.  To improve your abilities you have
to "train"!  That has to be done at or beyond the limits.
So to hear better train yourself with "weak signals".  To improve
your CW push your speed.  To qualify as a Marine Recon or NAVY Seal,
well .... good luck!  You know they train beyond the limits.  I have
been lucky to work alongside both who were retired vets!

My hearing is very poor, not from rock music but industrial
noise.  In the 1950-60's no one bothered with hearing
protection.  But I do know my ability can be improved with training
at levels I want to succeed at.

Thanks for the story.

Well maybe second to last. :-)   (But I doubt it.)

The most important thing I can do with my fading hearing (I'm 69
and fading hearing goes with the age) is to eliminate background
noise. I'm sitting in my shack and I can hear the jackhammer
outside, cars on the street, my wife walking in the living room,
the freezer humming away, and the backup drive on my desk
seeking as Time Machine does a backup. One of the greatest
blessings is when we have a power failure and most of that
background noise stops.

I use headphones which helps reduce the audio QRM. The CM-500
headphones help a lot, but what really works wonders are my
Sennheiser noise-canceling headphones. Turn them on and the
noise just disappears. I have used them while working ARES/RACES
for the Los Gatos Christmas Parade. They help there too,
although a lot of the parade noise still comes thru.

Cheers - Bill, AE6JV

"Sennheiser NoiseGard™ 2.0 technology provides up to 90% active noise cancellation"
http://en-us.sennheiser.com/noise-cancelling-headphones

90% reduction may sound good but it's only ~10 dB, which is typical for most active noise cancelling headphones.  If you're serious about noise reduction, you should be looking for 30 dB, which is available in both "in-ear" and "over-the-ear" style passive headphones:

I like the Sennheiser HD 280 Pro, which claims "up to 32 dB of ambient noise attenuation."  I have Bose QC2 active noise cancellation too but prefer the Sennheiser.

They seal out amplifier blower noise and noise from a furnace and water heater's exhaust fan that are about 20' away.  The sound is crisp, they sit around my ears, not on them, and are comfortable for many hours in a contest.

I realize the limitations of eHam reviews, though they score well - http://www.eham.net/reviews/detail/2951 .
