Hi Tom,
Yes, there certainly is a conflict of interest involved when expensive
devices are sold by the prescribing physician. Same deal with
eyeglasses. :) On the other hand, human senses are logarithmic in their
response, and our brains compensate a lot for any deficiencies. For that
reason, we get accustomed to loss of high end, which is quite common for
people our age, and made worse by noise exposures like yours. My XYL and
I both have significant hearing loss, mine a bit less than hers, and
we're considering hearing aids. BTW -- when you get to that, W6OAT is on
his second hearing aid, and he loves the new one he got from Costco.
Yes, you can use RXEQ to compensate for at least some of your hearing
loss. My friend K6DGW has rather severe hearing loss, and at my
suggestion, he's done exactly that. What you would do is set all of the
lower bands for maximum cut, and boost the higher bands. As a starting
point, set the four lowest bands to maximum cut (-18 dB), set the fifth
band to cut about 9 dB, set the highest band for about +10 dB, the band
below it for about +6 dB. Listen to the result, and tweak the settings
of the higher bands "by ear."
See you in Dayton?
73, Jim

Last week I had two audio test performed, performed by two different
persons, on my hearing. Do you think it would be advantageous for one to use
their audiogram plots to set the receive equalization in the K3? At age 75
(and spending years on a Nave aircraft carrier) of course my low frequency
range is 'normal' and then my high frequency, starting around 800 Hz starts
dropping drastically. I do have some doubts about these audio test because
if your hearing is 'good', they have no way of selling their over-expensive
hearing aids.
