Computer simulations of acoustics

Hi all! My first post here - It's been a pleasure lurking up until now :). I am trying to gain better understanding of acoustics by writing a computer program to simulate the wave equation - so far in just one dimension using a simple Finite Differences scheme. I'd appreciate some help with a few points I'm stuck with. 1. Is it possible to model a "speaker" with the 1D wave equation? What sort of source does it correspond to? 2. I understand p=0 (zero pressure) at the boundaries equal to completely reflective walls, but how do I model absorption? What sort of boundary conditions do I need? If you know of a good paper on the subject I'd also appreciate it a lot. Thanks for the help! :)

Oz, welcome; I hate to send anyone somewhere else, but you'll find a lot more people willing/able to help with this here http://forum.studiotips.com/ I'm just "spread too thin" to have time to get into this sort of thing ATM, sorry... Steve

Thanks for the link, Steve - just got another forum to lurk around ;). I've got to say you're running a great forum here, I learn a lot from just reading posts. Keep up the good work!

Thanks; just noticed you've apparently missed the "location" request found here http://www.johnlsayers.com/phpBB2/viewtopic.php?t=3231 there will likely be more questions I can (or have already) answered, and it's much easier to recommend practical solutions if we know where in the world you're located; check out that link for more. Thanks again... Steve

Hey Steve & all, I live in Israel. However the wave equation is the same worldwide :wink: .

...but product availability isn't (unfortunately)... :roll:
