I've been spending a lot of time recently trying to optimize my stereo setup. REW measurements, speaker placement and toe-in degrees, 1 or 2 subwoofers, room treatment products, equalization...
But, the most revealing change (and improvement) was when I cupped my hands behind my ears while listening. Suddenly, there was so much more clarity and detail across the spectrum! It was really a veil lifting experience!
Some of you will probably think that this is a joke post, but I am absolutely serious.
What is the physical explanation behind this? Is it a kind of "treble boost" or is it more about removing sound reflections and getting more of the direct sound of the speaker?
