Evaluation of an implanted prosthesis

6-10. (canceled)

15-16. (canceled)

A prosthesis evaluation system, comprising:

• an earplug, comprising an occluding apparatus configured to occlude an ear canal of a recipient, and a sound capture apparatus integrated with the occluding apparatus and having a sound receiver that faces the middle ear when the earplug is effectively positioned in the ear canal;
• and
• an external component of a hearing prosthesis including a sound processor, the external component being in signal communication with the sound capture apparatus.

18-51. (canceled)

A method, comprising:

• occluding an ear canal of a recipient, wherein in the recipient is implanted an implanted prosthesis;
• operating the implanted prosthesis;
• capturing sound, at the location where the ear canal is occluded, the captured sound being generated by the implanted prosthesis during said operation.

A system, comprising:

• a vibration capture apparatus configured to capture vibration caused by a vibrating component of an implantable prosthesis, the vibration traveling through a middle ear of a recipient, and to generate a signal representative of the captured vibration, wherein
• the system is configured to evaluate the implantable prosthesis based on the captured vibration.

The system of claim 68, wherein:

• the implanted prosthesis is one of a Direct Acoustic Cochlear Implant (DACI) and middle ear implant.
