Social hearing measured with the Performance Inventory for Profound and Severe Loss: a comparison between adult multichannel cochlear implant patients and users of acoustical hearing aids.
The objective of this study was to investigate social hearing in successful users of multichannel cochlear implants (CIs) and to compare the scores with those of a group of hearing-impaired adults using acoustical hearing aids (HAs). Out of 88 patients who had undergone surgery, 75 CI users with a mean age of 55 years and a mean pre-operative hearing level of 113dB in the better ear were compared with 59 users of acoustical HAs with a mean age of 56 years and a mean hearing level of 82dB in the better ear. Seven CI patients were non-users and were excluded from the study. The Performance Inventory for Profound and Severe Loss, a questionnaire that measures different aspects of hearing handicap, was used. The CI group scored significantly better than the HA group in three of six evaluated categories, measuring subjective intensity of sounds, speech with visual cues, and response to auditory failure. Awareness of environmental sounds, speech with no visual cues and personal reactions did not differ significantly. The group of successful CI users scored higher on a self-report measure than did a group of users of acoustical HAs with moderate- severe-profound deafness. The best CI users scored better than the best HA users, and the worst CI users scored worse than the worst HA users.
