Avaliação da percepção da fala com ruído competitivo em adultos com implante coclear

Abstract

Aim: to evaluate the effects of different signal-tonoise ratios on speech recognition obtained by the use of cochlear implant (CI); to compare the speech recognition in noise with different types of multichannel cochlear implants (CIs) and to evaluate the degree of difficulty for speech understanding in noise in daily life situations. Study design: cohort transversal. Material and Method: Forty adults with post-lingual hearing loss implanted with Nucleus 22, Nucleus 24, Combi 40, Combi 40+ and Clarion. We evaluated the recognition for CPA sentences in quiet and in S/N +15, +10 and +5 dB. We also applied the Social Hearing Handicap Index (SHHI) questionnaire for self-assessment in daily life. Results and Conclusion: All the implanted adults presented a significant reduction in the scores for sentences recognition as the S/N decreased. The medians´ curve for sentence recognition reached 50% in the signal-tonoise ratio of +10 dB. There was no statistically significant difference in sentences' recognition scores and difficulty scores obtained with the SHHI, for all types of implants. The difficulties of implanted adults were rare in quiet and occasional in noisy situations according to SHHI questionnaire.

Tradução e Adaptação Transcultural para o Português Brasileiro do Questionário Hearing Implant Sound Quality Index - (HISQUI19)

“…Permission for the use of HISQUI 19 questionnaire was requested and approved by the investigators of the original instrument (Annex A).…”

“…The process of this study involved the following steps: translation and cross cultural adaptation of the HISQUI 19 according to Field Research (14)(15)(16) in the area and by applying the pretest and sample characterization.…”

“…Self-assessment questionnaires specifically developed for the assessment of CI users are still scarce. There are three questionnaires in international literature, "The Nijmegen Cochlear Implantation Questionnaire" (NCIQ), "Spatial Hearing Questionnaire" (SHQ) and "Hearing Implant Sound Quality Index" (HISQUI 19 ) (11)(12)(13) which have not yet been translated into the Brazilian context.…”

“…In this sense, the HISQUI 19 was the instrument selected to be developed for the adult CI population, which measures how good or how bad the individual considers the sound quality of the hearing implant to be in various everyday situations.…”

“…This paper analyzes the translation and cultural adaptation of the HISQUI 19 questionnaire, fulfilling the study of conceptual, item, semantic and operational equivalences, in addition to characterizing the population and the auditory performance of a group of implant users through the application of HISQUI 19 .…”
