---------------------- multipart/alternative attachment Hi Stephane A good place to start is the 5 lectures on Acoustics available on the Sweedish PTA website. This one has been up a few times before and has been the subject of quite a bit of differeing opinion, for not to say controversy. I dont have the math yet to calculate them, but I suppose some around do, but the fundemental runs roughly 10 time that of the transverse fundmental if I remember right. They are to some degree controlable, Conklin showed that... but its not quite as straightforward as it might seem when first reading his stuff. Understanding how Longitudinal waves move is fairly easy.. there is a lot of demonstrations on the nett. The sound we hear is longitudinal waves moveing through the air.
