It's important to note that the spectrum of the noise each of us hears is *not* the spectrum presented by the source.
Everything we hear is filtered by our ears. In the past youngster's ears were considered rather 'flat' from perhaps 20 Hz up to above 16 kHz. That changes as we get older and experience loud noises. Typically we develop holes in our hearing where we cannot hear anything at specific frequencies. Also, our overall frequency response is damaged. The nerve attachments in our ears for the higher frequencies seem to be the most delicate and are the first damaged by repeatedly hearing loud sounds. Even so, the overdone thudding base of many sound systems can destroy sensitivity in the low registers too. That's why people today, even young people in their teens, typically have hearing no better than those of a octogenarian of half a century ago. A desire for loud music has created what experts in the USA call a generation of functionally deaf people. My hearing is full of holes punctuated by chronic "ringing" (tinnitus) and my upper register is gone, thanks to long-term exposure to firearms and explosives in the Army. As a result, I like a lot of high frequency emphasis because it provides the most natural sounding audio after it passes through *my* banged-up ears. It's no wonder there are as many opinions about the "sound" of a rig as there are people listening...
