These are some auditory physiology documents which I find extremely interesting. Have a read: it's all pretty cool stuff relating to how we hear sound and how our brains process what we hear.

My feet are throbbing as I kick them up onto the coffee table in front of me. My ears, though ringing, are enjoying the peace of a quiet house. And my voice is pretty tired, but my heart wells up with a million words. (Sorry fingers, I know you're tired.. but my mind will sit and spin if I don't procure a filing system for all these thoughts.) So here I sit, exhausted mentally and physically, turning to an old-fashioned method of sharing thoughts -- the online blog.
