Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Just wrote a simple program to generate tones from 1KHz to 20Khz in 1Khz steps at an interval of 1 second. I was surprised to learn I could only hear to 9KHz (I'm 70yo.)
My daughter fared better at 15KHZ and my grand daughter got to 17KHZ.

Too many loud rock concerts in your youth, Paul?

If you can't hear the tone is it really happening?

If a tree falls in the woods, and no-one is around to hear it, does it make a sound?

If a man speaks and there is no woman around to hear it, is he still wrong ??

Great idea Paul. I'm eventually going to try dialing touch tones with the uMite.
When I get one of those round tuits.

@Centrex
It wasn't really a project I was working on something else and the idea just came to mind.
The code.
For x = 1000 to 20000 step 1000
PWM 1,x,50
Pause 700
Next x
Connect a small speaker between Pin4 and ground. Run the program and count how many tones you can hear.
