Wayne ... you posted a Fletcher-Munson curve in Hi-Eff forum last month. I don't understand it (and most things on this earth). If our ears follow this general curve at an early age, then why are speakers designed ruler flat if possible? Shouldn't they be a mirror image of the curve. And does that mean live music is contoured by the nature of the instruments and each ones power output? As we get older (me) the higher frequency hearing gets lower and lower. Shouldn't we compensate for that also when building speakers if we are the only listener? Zene

Well, sure. You can EQ for hearing loss or even just for personal preference.I think some hearing-aids for people who are severely hearing impaired probably EQ upper mids for intelligibility because there is a lot of information in the upper mids (like distinguishing a "D" sound fom a "T" sound). However, most people I know tend to like a more laid back treble as they age. Sizzly treble is popular with teenage boys that have the best hearing, and later, they'll want the warm sound of a tube amp with relaxed top end. That same sizzle seems to irritate the old-timers.

Whether to EQ or not depends on what type of listening experience you're trying to reproduce with your speakers. If you're trying to reproduce music as you would hear it NOW, there's no need to EQ. Loss of hearing in higher frequencies applies to the real world the same way it does to speaker systems. So if you're speakers are flat, music will sound the same as you would experience it in the real world. If you're trying to reproduce music as you would have heard it 20 years ago, then EQ would be required.

Garman pretty much nailed it, I think. Not to discourage you, but care should be taken when EQ'ing for loss of hearing is used. If one overdo it, the result might end up being more loss of hearing - be careful!
