Air speed in materials

Web Wolf · 5th September 2006, 12:04 PM

Hi, could someone tell me where to find a table with air speeds in fono isolators materials ?
This is very important for me to build a TL speaker !

Thanks
Bye

I'd imagine it change somewhat with frequency. IF you want to design a TL, use the sheets at www.quarterwave.com

If you are interested in the speed of sound through various materials, this is a start.

http://en.wikipedia.org/wiki/Speed_of_sound

If you need something more specific, please tell us the materials you are considering. Here is a list.

Rather:
http://www.quarter-wave.com/

Ed, those articles are of no use to TL design. He want sound speed for various stuffing or insulating materials - and I suppose of various densities as well..... Martin's worksheets are pretty much the only readily available resource.

First of all, thanks to all people who have responded me so fast !

Only one thing: what about a program that can import the woofer response and simulate TL effect ?

Thanks !
