CI calibrator (best for setting M levels. Right click the link to save the mp3 to your computer)
You should hear all 16 beeps about equally loud, whether electrodes are shut off or not.
Use headphones or direct connect since speakers and room resonances will affect the frequency response.
The beep # may not match an electrode #, so record frequencies of problem beeps, not their #.
Beep # Freq (Hz)
Version of CI calibrator with Click (use if tones are missing)
Virtual Piano (fun to play with, but not useful for testing your MAP, does not run on MAC unless in PC mode)
(if you have a CI, it's normal to not hear maybe one third of the notes, the low frequency ones)
