Chime Calculator: Unknown Material
Would you like to have a more accurate tuning of your material than just hoping that my "brass" has the same percentages of copper and zinc as your does?
This form will take your length and frequency measurements and provide the calculated reference value directly to the Chime Calculator
Instructions:
Take your material, cut to various lengths and As accurately as possible, measure the length
and frequency of your samples and enter them below. When you've exhausted your data, enter them below and
this script will provide the average value to the main page.
With that understanding, the way the program works is by using 3 parameters (thickness, elasticity, density) to calculate "K" (just consider this a variable name) and then using that to build a length/frequency table. But we can also derive "K" empirically by starting with tube length and its measured frequency and working backwards, which is what what we're doing here.
Preparation:
- Find an app that will try and give you a frequency from a sound your mic picks up (Or, OMG, you could use an analog scope to capture the wave)
- Find a piece of material you intend to use, measure it and use the app to estimate its first harmonic fequency
- Cut down the piece by a few units and repeat the above. (REMEMBER: MEASURE THRICE CUT ONCE)
- Enter measured lengths and frequencies in the below table
