In the midst of studying/lurking here at 3am the other night(morning?) I had an idea.  I figured it would be nice to have a quick tool to be able to tell you where dead spots would be in different frequency ranges, and some other things based on a few inputs.  Ideally I would program this on my TI-89 calculator, because it is the most road-worthy piece of electronics I have ever used.

First off, I am wondering if anyone knows of good resources for this kinda thing.  Math is ok, and probably preferred.  I've done some searching in the library and on google and found some references, but I'm looking for all I can get.

Secondly, if you had such a program, what would you want it to tell you?  I have some ideas of what I want, but maybe you guys can think of some other features.

I've started talking to some professors around here and they can help, but none really focus on speakers or rooms.  I can get help with the hard science, but I want to get some feedback from people who deal with this stuff every day.

Thanks in advance for your input.

This is kind of a start, not sure if it is what you need though
