I have hearing impairments also and have In The Ear (ITE) Seimens Centra
hearing aids (no longer available as ITE), with telecoils. I have found that
J-hooks <http://www.tecear.com/Music_Link.htm> worn and plugged into my AOR
TDF-370 DSP audio filter plugged into the line out of my OMNI-VII works
really well. While I have some problems with headphones and speakers, the
inductive connection by J-hooks to my hearing aids and audio reproduction
inside them rather than audio amplification by them has helped me hear and
clearly decode and understand voice and CW.
While my hearing aids have an automatic magnetic switching feature to
telecoil operation (auto switching occurs when I put on a headset), the
J-hook has NO magnet. I had my hearing aides re-programmed so that I can
manually activate the telecoil feature to use J-hooks. A secondary benefit
is NO headset fatigue or pinched ears when using J-hooks.

I have several in the shack for Hi Fi and ham use, I have some old
Realistic (RadioCrack) 10-band equalizers Cat. Co. 31-275 and 31-1989,
and a Sansui GM77, and all of these can be had in good condition for
under $50 on eBay if you shop carefully. New ones by Behringer, or
Technical Pro, or maybe Peavey can be had for around $99 or so.
Sometimes you can use one channel of a stereo model on one rig, and the
other on another rig, allowing for separate EQ of two rigs.
TenTec radios are cool because they sometimes have a LINE-OUT jack on
the rear (typically on the octopus accessory ACC-1 jack cable) and that
allows you to use the rig speaker, or an extension speaker, plus route
the audio at Line-Level to the EQalizer and powered speakers, and even
use the headphone jack separately and still have the audio routed to the
LINE-OUT line level jack (and maybe put your headphones into the final
speaker/headphone device) - or - you can route the speaker out to the EQ
and powered speakers, or the like, and you have some flexibility on
where to put it. I use the LINE-OUT to the EQ and then input that into
a TimeWave DSP 599zx audio filter, and use its separate output to
powered speakers and/or headphones.
AND, you can usually bypass the EQalizer if you like.
Hope this helps... I can do photos, too... just ask.

Which brand of graphic equalizer are you using…I am very hearing
impaired…need plenty of low frequency in audio and have nothing above 1200
hrs.

For substantial selective hearing loss, or for detailed adjustment and
compensation over the useful frequency range, I would consider a multi
band graphic equalizer to tailor the audio to your needs.
The Omni VII, for example, has a limited two band EQ setting, which is
adequate for my needs (I set it on FLAT/0 anyway), but for greater
detail and more specific frequency adjustment, I would probably use a 12,
15 or more band EQ to compensate the audio. Simple to deploy if you are
using amplified speakers such as computer speakers or the popular small
nearfield studio monitors. I don't use one on ham radio, but my wife
and I enjoy listening to old time radio programs, and we tailor the audio
for best presentation of the speech frequency spectrum, and it makes a
substantial difference. She has partial hearing loss, so it really
helps to tune the audio to her limitations.

there is equalization available when pressing the AUDIO button. I have
never
played with the settings. Is it possible to contour the audio to a
hearing
range?
