Hearing issues and signal attenuation

"with my aids up to 4 EQs are possible"

I just read Broadstone's reply and realized someone might misinterpret what I meant to say just prior to that. My devices have four unique memory settings. Any combination of frequency gain or reduction, noise filtering, and directionality can be programmed (by the audiologist) for each of those four. The range of frequency adjustments is from 500 to 8K Hz.

Many hearing aid manufacturers offer a recommended response for music but I found a custom setting was needed for the most natural musical tones.

Maybe I should start a separate thread for this question but I'll try it here in regard to adjusting the EQ. Now that I have the experimental equalizer in place I've been attempting to achieve the R/L balance not just for volume balance but for frequency balance as well. This activity is not as straightforward as I, without much thought, anticipated because changes especially in the mid to upper frequencies affect the directionality and, therefore, perception of where the sound source is strongest.

So, this is the approach I've been trying. Starting with right and left channels set at neutral volume and flat frequency settings I used an audio test CD and stepped through frequencies listening to how closely centered the signal seems. As I come to a frequency that appears weighted to the right side I adjust the dB on the left side of that approximate frequency upward until the tone centers. I do this through to 8 KHz where my ability to hear pretty much ends.

Here's where it stops being simple. It seems that increasing the dB of those frequencies resulted in my overall perception of balance change when listening to music, migrating now to the left side. Using music to adjust balance, though, has other issues, mostly I think, based on how the music was recorded in the first place. For example, I listen to some small jazz groups which seem to record in a way that represents poisoning of various instruments accentuating, for example, that drums are located at stage right. This seems especially to be the case with the older recordings when there seems to have been more effort given to demonstrating stereo effect.

I don't claim to know what I'm doing here but, regardless of that, I'm very much satisfied, so far, with the listening improvement resulting from the addition of this equalizer.

Since your initial results are positive, I think you should get a better EQ. 12 bands are not enough for the level of precision that you probably need. Also, you are taking a big hit in sound quality putting that old, analogue EQ in the chain. In one of the other quotes, someone mentioned the Behringer digital EQ. That would be a good place to start. I have one myself. It has tons of features that you may find of use besides just a graphic EQ. Also, it should sound a lot better than what you currently have, especially since you can use the DAC in your Peachtree. If you have a Guitar Center nearby, you can get it from them and return it if it doesn't work out. GC has a very good return policy.

A good start Broadstone. Now that you've experienced what EQ can do and learned the basics, you can move up to a better EQ.

Lowrider, I will do as you suggest and have started looking into the pro EQ's and how to incorporate one into my system. I guess, though, that my hope for a simple solution is dashed. I was thinking that an EQ would have simple RCA in and out connections like in the old days but it appears that's not going to happen. In reading a couple of articles on how to use a pro audio EQ with a home stereo setup, it isn't a very straightforward operation. I don't mind expending some effort but having to solder resistors across connections and add an an external DAC, etc. seems a bit more involved than it should be. Don't get me wrong, I'll do whatever it takes but is there something out there that will help me do this that is a little less demanding?
