My wife says I'm a little obsessed with sound :) I'm always either copying sounds, or making some kind of noise :) One thing I like to do, is find the resonant frequencies of a room. If you start out with a low hum and gradually increase the frequency, you will hear the resonant frequencies; your hum is amplified by the room. I imagine that the music venues that are known to have "excellent acoustics" are probably resonant to frequencies that are most pleasing to humans. (but some rooms are too irregular or have too many things to do it, but it definitely works in a small room like a bathroom :) )
