Mathematical Cochlea Slide Ruler Pointing at Middle "C"
|
How to Use
|
- Adjust the pointer to the frequency you would like to start at.
For example, middle "C" is 261.
- Spin the internal ruler (blue in color) until the indicator of
"do" sound is overlapped by the pointer.
- Fix the internal ruler and now you can see the frequency of
any pitches by adjusting the pointer again.
