Completing a Microphone Check

To test the internal Microphone of Auria, you will need to use a mini amplified speaker

(available from an electronics store).

You should perform a microphone test when the Processor is new, to establish a base-

line from which you can monitor the internal Microphone for any sound-quality issues.

The microphone test only assesses the internal Microphone of the Processor and will

not provide information about the headpiece cable or T-Mic.

Procedures

To assess the Microphone, you will need an empty program slot on the Auria Processor.

speak with your student's parent or audiologist to determine which program slot is

empty.

1. Remove the Auria Processor from the child. You will not hear any sound from

the speaker and will not be able to monitor the Microphone if the student is

wearing the Processor.

2. connect the direct connect Earhook and direct connect cable to Auria.

3. connect one end of the Audio Interface cable to the direct connect cable

and the other end to the port on the mini amplified speaker (top port marked

input) or the appropriate audio input port on your computer. To monitor the

Microphone's output while wearing headphones, plug headphones into the

headphone port of the speaker or computer.

4. hold the Processor at an arm's length away from the speaker to prevent

feedback and distortion. (Figure below.)

5. Turn on the Processor (attach battery) and select the microphone test position

(empty program slot), using the Program control selector.

6. Increase the Volume control on the speaker while speaking normally.

7. Monitor the output from the speaker. sounds and speech should be clear but

amplified. The quality of the sound will depend upon the quality of speaker you

are using.

Microphone testing is simple and important. When combined with the system sensor

or FireFly Earhook, parents, educators, and clinicians have comprehensive diagnostic

tools to ensure that young children get the most out of their cochlear implants.
