Jon O on the Ascend forum referenced a whitepaper from Harman International recently (if you aren’t familiar, Harman is the parent company of several companies including Harman Kardon, JBL, Infinity, Revel, Lexicon, Mark Levinson, AKG and more) and it has me poking around their whitepaper repository.

Over the years, Harman and its child companies have employed many of the great minds of audio, so the repository has some good stuff.

Jon O was linking to a paper on room acoustics at low frequencies for multichannel audio. It covers some good concepts about modes and placement of both the speakers and listener. (PDF here)

I have started reading the Master Handbook of Acoustics to learn more about acoutics and room behavior. So far it seems like a pretty good resource, although the author makes some assumptions about the reader’s understanding of mathematics and ability to pick up on things quickly. To pick up on some of the topics hands-on, having a copy of ETF (the author uses ETF in examples, so having this particular program is useful, but other software could accomplish the same thing) and appropriate hardware to to basic measurements is helpful.
