Speakers sound brighter at evening / night?

"What is it with this urge to explain away the things we hear? Not explain- explain away. The implication is you didn't really hear what you know perfectly darn well you did. It didn't really happen. You only think that it did.

Poppycock! "

millercarbon, I firmly believe from my own experience that there can be profound differences in perception of the same sound at different times due to the state of mind of the listener. Some people, perhaps yourself, may be better at purely objective listening than others. I know my limits and have to be careful. Flying an airplane in clouds taught me really quickly that my inner ear sense of up and down is not well fixed, but is highly calibrated by what my eyes are seeing and what the rest of my body is feeling. I've experienced my sense of timbral balance change significantly at times. I came home one time after a long drive and turned on my system. The bass was severely lacking. I measured. It measured just fine. I listened to the same music on my headphones using an entirely different battery operated playback chain and the bass still sounded thin. It had to be my perception being temporarily altered, not the equipment output changing. 

Why is that surprising?  Food tastes better/(ok--different) in the evening.  Sex is better/different.  Drugs are better/(different).  Falling asleep is different.  Having a phone conversation is different.  Why shouldn't music sound better/(different)?   

All fine and well. If you say you can't tell your up from your down then fine, I believe you. If something sounds wrong and you need a meter because you can't figure out its because your ears have been hammered by a long car trip, okay, fine. I believe you. Totally. 

Here's the thing. Why are you unable to make the same allowance? Why are you incapable of imagining anyone else being able to do something, simply because you cannot? If someone describes a Michael Jordan dunk it would never even occur to me to try and explain it away with a long diatribe on how incapable I am of making even a foul shot. Whole bunch of people are quite certain he flew 20 feet through the air around three other guys looping the ball behind his back and swoosh through the net. Sometimes incredible things we ourselves never could do in a million years, the next guy makes it look easy. 

That's the way it is with me and music. And that's the way it is with a lot of other people too. Don't try and explain it away. Deal with it.

Direct receptors of light? Yep.

Charles Ott proved that way back when - trouble was, psychology was even less of a science then, than it is now. I used to demonstrate some of his effects to students, just for devilment.

There is a difference between having the same type of skills as other people, just better or much better and claiming to have skills that are beyond our genetics and physical capabilities including the way our memory works.

It is like so called photographic memory which does not actually exist. People who claim that makes mistakes on recall and their memory is prone to suggestion just like anyone else. They do have better memory but not photographic.
