Help - using a band equalizer

I recommend NOT using an EQ to try to compensate for hearing loss. Any range of sounds you INCREASE in volume will increase your rate of hearing loss over time. It's better to just let the sound over 8,000 Hz slip away. You aren't missing ANY notes from ANY instrument if you can hear 8,000 Hz. All you lose are harmonics. A cymbal will still sound like a cymbal when you remove everything above 8,000 Hz and you won't be doing something that increases your rate of hearing loss. If you drive a car with the windows open STOP DOING THAT IMMEDIATELY. The buffeting of your eardrums caused by the wind is among the largest excursions your ear drums will create of ANY sound. Those large excursions are what fatigues the fine nerves in your chochlea and causes them to lose the ability to respond to high frequencies over time. The more you can remove large excursions of your eardrum, the longer your hearing will last without further degredation. Obviously, riding a motorcycle without a helmet to stop the wind buffeting the eardrums is also a very bad idea. At the very least, use earplugs so the wind can't cause large excursions of your eardrums. Skydiving without ear plugs is a bad idea from a wind-buffeting point of view, but I have no idea if the use of ear plugs while skydiving is possible or not due to air pressure changes as you descend. But you get the idea... don't make sounds you can't hear louder to avoid further hearing loss. If you end up with hearing aids, use them carefully and at the lowest effective settings as possible to preserve as much of your hearing as possible over the next 30 years.

Well, of course they will not tell you that using hearing aids can accelerate hearing loss. Why would they do that? There is no other solution they can offer. I was brought to this knowledge by a loudspeaker manufacturer who's been in business for 45 years. He chose hearing loss and hearing restoration as his charitable cause for that entire time. He has been involved with that since the 1970s and has campaigned endlessly for better techniques and education about hearing aids. Hearing aids are tools, but should always be used with the least amount of volume boosting as possible and for short periods of time in order to reduce any chance of the hearing aids causing further hearing loss. The more you need the hearing aid, the louder the EQ has to be for effectiveness... but the louder the hearing aid is set, the larger the chance of causing more hearing loss. You can choose to believe this or not... your belief is not required for this to be fact.
If you create the EQ in your audio system, every time you listen to anything at any significant volume level, you can be contributing to further hearing loss. So the more you need hearing aids, the faster they will further degrade your hearing just by using them. When you lose the ability to hear some range of sound, the ability of sound in that frequency range to further damage your hearing does not go away. Again, your belief is not required for this to be factual.
