CI calibrator (best for setting M levels)

You should hear all 16 beeps about equally loud, whether electrodes are shut off or not.

The beep # may not match an electrode #, so record frequencies of problem beeps, not their #.

 Beep #              Freq (Hz)

1                                             315

2                                             455

3                                             540

4                                             642

5                                             762

6                                             906

7                                             1076

8                                             1278

9                                             1518

10                                         1803

11                                         2142

12                                         2544

13                                         3022

14                                         3590

15                                         4264

16                                         6665

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)
