These values that I test on myself are values based on this resource: http://www.phys.unsw.edu.au/jw/hearing.html
The scores are from the chart on that page.
The sound-level on my laptop HP HDX18 will be set to the value of 74 every time I do this test. My CI’s volume wheel is set to exact the middle position (turning all the way down reduces sound volume by 20% and turning up increases 50%!). Then I have the same test-settings every time. “Wire” means that I use a direct connection between the computers jack-plug-outlet and my Advanced Bionics processor. No sound pollution possible.
Every level of registration is a notion of sound. That means that I do not necessarily detect the difference in tone/frequency. Green is where I hear the sound (yet so far all the sounds sound mostly the same, i.e.. a very thin squeaking tone or beeep), red is only a short beep, blip, bip or ding.
( I can hear violin of my own breath, broken glass of paper being crumbled and a ding every time one of my fingers hit a key on the keyboard!)
If anyone know of more sound-test or sound-generating resources on the internet, I’d be grateful for any tips!

You might find a sound generating source here. http://www.phon.ucl.ac.uk/resource/
It’s all a bit over my head really
