more adjectives to help define 'fatigue' vectors?


My apologies in advance for posting a naive question, and perhaps erroneously posting this in 'speakers' rather than 'amps' as well, but my efforts to find this answer via search are failing me...

I understand, I believe, what 'fatigue' itself means. But I don't understand in the slightest the causes/mechanisms of it in a listening situation.

I assume there must be myriad causes - but can they be grouped or categorized...and explained in something approaching layman terms?

Fatigue induced by speakers, amps, poor power, etc...do they all have something in common that I'm missing?

Or are they all completely different conditions that result in the same general 'fatigue' outcome?

Perhaps fatigued, perhaps not;

The decreased capacity or complete inability of an organism, an organ, or a part to function normally because of excessive stimulation or prolonged exertion.
love that Entrope.

...is it generally safe to say that the type of excessive stimulation audiophiles experience, and describe as fatiguing, is generally high frequency information? That the HF portion of the experience is where folks are finding themselves overly exerted?
I've experienced fatigue and it was the high frequencies. If you really want to experience it, I know for sure that Rotel and B&W speakers with the metal domes will fatigue most anyone. Add in the silver speaker cable and prepare for fatigue gone wild.

Its all about room acoustics. Bad room acoustics will do this

Bob, that might be what i've got going on, although this question was really academic at the time I posted it...I was reading the word fatigue used here and had no idea what part of the spectrum it came from, if everybody was talking about the same thing, or what it was. I'm less than a year into this. The consensus I'm gleaning is that it's a HF phenomena, some kind of shrillness. I can certainly see how that that kind of energy would be made much worse in a bright reflective room for sure.

bridging these two posts, guess my question would be...can a non-fatiguing system be deployed in a brighter-than-ideal room and have it remain not-fatiguing?
