Acoustics

Acoustics have a lot to do with the effects of music (or just simple sound) on the listener. This is a link to an extreme example, Mayan ball courts. The structure was apparently built with sound effects in mind. The thing about acoustics is that providing for them in structures seems to be as much art as science. One often hears of new concert halls with poor acoustics and of older halls with wonderful acoustics. Part of the problem might be that with the advent of recorded music, people (including architects) are spending less time in concert halls, so they're naturally less familiar with what does and doesn't work.
