Speech Intelligibility Index and the Ling 6(HL) test: correlations in pediatric hearing aid users
Marilia Rodrigues Freitas de Souza, Maria Cecília Martinelli Iorio
Resumo
Objetivo: Avaliar a audibilidade de fala em crianças usuárias de próteses auditivas e correlacionar o Índice de Inteligibilidade de Fala à detecção de fonemas. Método: 22 crianças e adolescentes usuários de próteses auditivas passaram por avaliação audiológica básica, verificação in situ (e consequente obtenção do Índice de Inteligibilidade de Fala - SII - para condições com e sem próteses auditivas) e pesquisa dos limiares de detecção para fonemas por meio do teste Ling-6(HL). Resultados: O SII médio foi 25,1 sem próteses auditivas e 68,9 com amplificação (p <0,001*). Os limiares de detecção de fonemas em campo livre, em dBNA, foram, sem amplificação /m/=29,9, /u/=29,5, /a/=35,5, /i/=30,8, /∫/=44,2 e /s/=44,9, e com amplificação /m/=13,0, /u/=11,5 /a/=14,3, /i/=15,4, /∫/=20,4 e /s/=23,1 (p <0,001*). Houve correlação negativa entre SII e os limiares de todos os fonemas na condição sem próteses (p≤0,001*) e entre SII e o limiar do /s/ com próteses (p = 0,036*). Conclusão: Os limiares de detecção de todos os fonemas são menores do que na condição sem próteses. Há correlação negativa entre SII e os limiares de todos os fonemas na situação sem próteses e entre SII e o limiar de detecção do fonema /s/ na situação com próteses auditivas.

Abstract
Purpose: To evaluate speech audibility in schoolchildren hearing aids users and correlate the Speech Intelligibility Index to phonemes detecion. Methods: 22 children and adolescents hearing aids users, underwent audiological evaluation, in situ verification (and consequent obtaining the Speech Intelligibility Index - SII - for conditions with and without hearing aids) and detection thresholds for phonemes by Ling-6 (HL) test. Results: The average value for the SII was 25.1 without hearing aids and 68.9 with amplification (p <0.001 *). The phoneme detection thresholds in free field, in dBHL, were, without amplification /m/ = 29.9, /u/ = 29.5, /a/ = 35.5, /i/ = 30.8, /∫/ = 44.2 e /s/ = 44.9, and with amplification /m/ = 13.0, /u/ = 11.5 /a/ = 14.3, /i/ = 15.4, /∫/ = 20.4 e /s/ = 23.1 (p<0.001*). There was a negative correlation between SII and the thresholds of all phonemes in the condition without hearing aids (p≤0.001*) and between SII and the /s/ threshold with hearing aids (p=0.036*). Conclusion: The detection thresholds for all phonemes are lower than without hearing aids. There is a negative correlation between SII and the thresholds of all phonemes in the situation without hearing aids and between SII and the detection threshold of the phoneme / s / in the situation with hearing aids.
