Post-Implant for Recipients

Mapping

Mapping involves the programming of the external speech processor. The audiologist creates a listening program specifically for the recipient. At first, many mapping sessions are required to fine-tune and find the best listening parameters for that person. The recipient is constantly adapting to the device and mappings are required to adjust the listening program for optimal sound over time.

The mapping schedule usually follows this sequence:

Maintenance and Troubleshooting of the Speech Processor

The speech processor needs to be checked every day to ensure optimal sound quality. The batteries must be charged or changed appropriately, the cables checked for good transmission of sound, the microphone must be clear, and the volume and other settings should be appropriate. The Dry & Store (electronic dehumidifier) must be used every night to rid the speech processor of moisture that may have accumulated during the day.

If any part of the system is malfunctioning, the recipient will not hear properly, will hear intermittently, will hear static, or will not hear at all.

Therapy

Auditory-Verbal Therapy or aural rehabilitation therapy is critical for success with the implant. The primary function of the cochlear implant is to provide spoken language information through hearing sensation and active listening. The cochlear implant provides the hearing sensation and AV therapy provides the tools for learning to listen.

Benefits of the cochlear implant range from detecting sound to speech understanding without lip-reading.
