Hi,

I was wondering if you could tell me more technically how whistles work. ie.  how either low frequencies or high frequencies are generated by the whistle.  Is there a critical feature eg step size, exit hole shape/size
etc in the whistle geometry that produces differently sized vortices that when they shed off the back end, generate certain frequencies depending on their size and speed?
I have never cut one open and don't have one on me to understand how they work properly.

What effect does the ball or pea have in a whistle?  Does it aid in trilling by producing more even pressure fluctuations?

I would love to hear back from you if you have any information.

Please obtain/read the book called "Vortice Noise". The pea in the whistle adds charater to the othewise pure tone sound from a whistle.
