Not sure if this helps, but two competing sound devices in one room is likely something folks can relate to. For example one of my kids was watching TV and felt I was speaking to loud on the phone (noise to my kid) therefore they had to increase the signal (volume of the TV to compensate). you can extend this analogy to listening to an ipod (signal) on a noisy bus or train (background noise).

(Just for example, if I recall correctly, John Denver did compose "Leaving on a Jet Plane" and yet probably the most famous recording of it was by Peter, Paul, and Mary.) I do remember a recording by John Denver and hearing him play it live at a concert in El Paso umpteen years ago. And yes, for my sins, when I used to be a professional SSWG (singer songwriter with guitar) I have performed it only on request -- surprising how many people actually do like it, no accounting for taste. It is even mentioned in Ed Abbey's book, "The Monkey Wrench Gang". Or to paraphrase, "I know a lot about music but I don't know what I like". And another thought for the musically-minded, based on the physics of a vibrating string (or an air colume for brass or wind instruments), when you half the length, you raise the pitch by an octave, and proportionally with other shortening. Or if you increase the length to twice the original, you decrease the pitch by an octave, and proportionally for lengthening. The entire overtone series (the other not played directly but heard by the ear notes) stays the same in the different octaves, but the intensity of sound of each of them may be decreased or augmented depending on the circumstances. The empahsis or not of various notes in the overtone series determines the "timbor" of an individual instrument, which is why your average student violin doesn't sound exactly like a Stradivarious, even when the same musician plays the same note on each. And I do like the analogy to trying to simmer a succulent sauce in a small pan over a large gas stove burner. Even some of us of the male persusasion enjoy cooking good things. I find it a great stress-reliever (unless you let the flame get too high and scorch the sauce and must then discard it and start over -- my old gas range has a mind of its own and raises the flame without anyone touching the dial, and so requires constant attention).
