Each year, I notice the same phenomenon, but quickly forget about it, especially since I automatically put it in the "psychosomatic" category. But this year, it just hit me to post the effect and see if anyone as actual info and verify that it is caused by sensory perception.
The phenomenon is as follows: when it is cold enough outside, my iPod starts sounding better (clearer, neater, cryspier). Yesterday and Today, temperature are between -15C and -20C in Montreal and the sound change took me by surprise yet again.
So, is it due to the cold changing our (my) senses and making us (me) perceive sound differently, or is the cold changing enough the frequency response of my (our) headphones that I (we) notice a... noticeable change?
