So I have said before and will continue to say until contrary evidence comes along that the people who think there's no difference, well they are right. For them there is no difference. Until they learn to differentiate there never will be. Because its not a matter of psychology, or opinion. Its a question of skill. And skills can be learned. If you want to be a good listener, its a skill you can learn. If you want to. But you do have to make the effort.Good post....
Auditory hability are measured in Hertz perceived or not..... Listening hability are not measurable in this way....
All those debunkers are lazy or simplistic, when they equate perception of grain with illusion... :)
