Results of studies performed in our laboratory suggest that cochlear implant recipients understand speech best if the following speech processor parameters are individually chosen for each person: minimum and maximum stimulation levels on each electrode in the speech processor program (MAP), stimulation rate, and speech coding strategy. If these and related parameters are chosen to make soft sounds (from approximately 100 to 6,000 Hz) audible at as close to 20 dB hearing level as possible and loud sounds not too loud, recipients have the opportunity to hear speech in everyday life situations that are of key importance to children who are learning language and to all recipients in terms of ease of communication.

Objectives: We sought to assess the associations between self-reported listening habits and enjoyment of music, and the following variables: Age at implantation, gender, prelingual versus postlingual deafness, duration of deafness, duration of cochlear implant (CI) use, type of CI, speech coding strategy, and speech perception abilities. Methods: A questionnaire on listening habits and enjoyment of music before the onset of deafness and after implantation was sent to 85 adult CI recipients who had been using the devices for at least 6 months. Results: Of the 53 responders, 39 (73.6%) listened to music after implantation. Listening to music was not significantly related to age at implantation, gender, duration of deafness, duration of CI use, type of CI device, speech coding strategy, or open-set speech perception abilities. The 14 nonlisteners were postlingually deafened. The ratings of enjoyment were the same for 22.6% of patients, improved for 26.4%, and worse for 50.9%. Only 2 of 13 patients who played a musical instrument and 14 of 24 patients who sang before the onset of deafness resumed their musical activities. Conclusions: Despite the decline in listening habits and in the enjoyment of music after cochlear implantation, most patients do listen to music. The changes in listening habits and enjoyment were not related to the selected background variables.

Eight subjects participated in a comparison of the multipeak (MPEAK) and spectral peak (SPEAK) speech coding strategies of the Nucleus TM 22-channel cochlear implant system as part of a long-term monitoring study. Sound-field threshold levels and speech recognition performance on the Bamford-Kowal-Bench Sentence Test, NU-6 Monosyllabic Word Test, and Connected Speech Test or CID Everyday Sentence Test were analyzed for the two speech coding strategies. For the group, speech recognition performance was significantly higher with the SPEAK speech coding strategy than with the MPEAK strategy on all speech tests. For individual subjects, scores with the SPEAK strategy were significantly higher for some subjects on each of the speech tests. None of the subjects scored significantly higher on any of the tests with MPEAK.
