What is I play noises and music at the same time? Will it hasten the process?

Burn in doesn't really exist although Tyll from the famous headphone review site seems to have found something... With an akg headphone. Though through all the scepticism here I think more evidence is needed than a single test. Let's say for now: burn in doesn't exist until proven otherwise, and I mean really proven. Not audiophile proven.
