Calculator page

For anyone who wishes to choose his materials while understanding how sound will transmit through/bound back from the boudary between the materials, above is a page with all sorts of calculators, one of them being an acoustical impedance calculator that allows you to choose 2 materials and see what happens.

Might be usefull...

And you know what?
In order to have more choices than are available in the tables supplied in the calculator, all u need is to know the density and the velocity of sound in the 2 materials. So below are 2 links that contain this information about lots of materials.

Enjoy (or not...)
