ABSTRACT
ABSTRACT This is a pilot study that aims (1) to help design a protocol for fitting and optimizing cochlear implants and hearing aids, (2) to help design a test battery that can help monitor children's progress and (3) to assess the benefit of using a cochlear implant with a contralateral hearing aid. Seven children between the ages of seven and 15 years completed the study. None of them had worn a contralateral hearing aid (HA) since cochlear implantation (five to seven years after implantation). The Listening Inventory for Education (LIFE), Life Situation Questionnaire (LSQ), and Client Orientated Scale of Improvement for Children (COSI-C) questionnaires together with subject's feedback were used as subjective measures, and speech perception tests - the City of New York (sentences list) (CUNY) and Bamford-Kowal-Bench (sentences list) (BKB) depending on child's speech perception skills - in quiet and in noise were used as objective measures. The results showed mixed subjective feedback, even though objectively all children improved their speech perception scores when wearing cochlear implants and hearing aids. The COSI-C proved to be the most successful tool to collect feedback from parents.
