Possibly NSFW question about the acoustics of peeing. [more inside]
Heard an NPR story 7(ish) years ago about a guy who measures the pitch of various sources of barely-audible workspace/home background noise (eg. harddrive spinning, refrigerator compressor running, and the flyback transformer on your television) and seeing what chords they made.

Can anyone offer me some suggestions for how to make a relatively inexpensive sound trap (i.e. like those echo reducers that large auditoriums have). Info about materials, shapes, etc. would be helpful. [more inside]
Does sound carry downwards? [more inside]
What is the name of the simple dish-shaped device used to project and receive sound across a large room? [more inside]
