sqrt means square root, by the way

[kliao93]

lol i figured after, thank you! I have to do this for a project, and I was wondering (begging in fact)

if I could get the dimensions (inside outside diameter, and lengths of pipe) of what you are currently playing?

And are you just using foam circles around them?

Thank you so much!!!! I'm not sure if thats, 1 inch (inner diameter emt) or what, thank you again!

If you buy 1/2 inch EMT you should be in the right ballpark. I find that the 1/2 stock has the best tone (it is deeper than 3/4 or 1-inch stock). You don't eve need to use the dimensions in the calculations if you use the method described below. You can determine the constant k using the pipe dimensions, but IMO, you'll get a more accurate result by testing the stock to determine its particular constant.

The foam circles are cut from pipe insulation to provide a playing scenerio.

pipe length = sqrt (k / Frequency)

Very non-linear :) Start by measuring your materials constant. Measure the length In *meters* of a piece of pipe that you have cut. Use sigview to determine the freq of the fundamental. Plug those values into the above equation, then solve for k. k is your constant for that piece of tubing.

Next, pick your desired frequencies, use k from the last part, and then solve for the required pipe length.

This should get you really close.

Subtle and beautiful!

A few mistakes here and there, but that's ok, because you are awesome ;)

thank you very much! the equation worked perfectly for my project and i appreciate the help!

[kliao93]

sorry what does sqrt mean? i need to do this for physics but we use different terms or whatever. and what is sigview?

thank you for this video, and btw the links aren't working unfortunately. thanx again

Do you know what kind of function the relation between pipe length and wave length is? It's certainly not linear according to the 4 pipes I cut. I'm using "sigview" and a ruler.

[RainMan002]

So I'm trying to do this and I'd like to know if you have any idea what the correlation between length and frequency is... I'm a bit baffled. it's not at all standard air in pipe resonance.
