Abstract Introduction: The auditory processing is related to certain skills such as speech recognition in noise. The HINT-Brazil test allows the measurement of the Speech/Noise ratio however there are no studies in the national literature that establish parameters for the child population. Objective: To analyze the performance of normal-hearing subjects aged 8-10 years old in tasks for speech recognition in noise using HINT test. Methods: Sixty schoolchildren were evaluated. They were between 8 and 10 years of age, of both genders, and had no auditory and school complaints, with results ranking within normality for the Basic Audiological Assessment and the Dichotic Digits Test. HINT-Brazil test was applied with headphones, with the Speech/Noise ratio in conditions of frontal noise, noise to the right, and noise to the left being investigated. The software calculated the Composite Noise, which corresponds to the weighted mean of the tested conditions. Results: There was no statistically significant difference between the ears, nor between the genders. There was a statistically significant difference for age ranges of 8 and 10 years, in situations with noise, and for Composite Noise. The age group of 10 years showed better performance than the age group of 8; the age group of 9 years did not show statistically significant difference regarding the other age ranges. We suggest the values of mean and standard deviation of the Speech/Noise ratio, considering the age ranges of: 8 years - Frontal Noise: −2.09 (±1.09); Right Noise: −7.64 (±1.72); Left Noise: −7.53 (±2.80); Composite Noise: −4.86 (±1.31); 9 years - Frontal Noise: −2.82 (±0.74); Right Noise: −8.49 (±2.24); Left Noise: −8.41 (±1.75); Composite Noise: −5.63 (±1.02); 10 years - Frontal Noise: −3.01 (±0.95); Right Noise: −9.47 (±1.43); Left Noise: −9.16 (±1.65); Composite Noise: −6.16 (±0.91). Conclusion: HINT-Brazil test is a simple and fast test, and is not difficult to performed with normal-hearing children. The results confirm that it is an efficient test to be used with the age range evaluated.
Resumo Introdução: O processamento auditivo está relacionado a determinadas habilidades, como o reconhecimento de fala no ruído. O teste HINT-Brasil permite a mensuração da relação Fala/Ruído, porém, não há na literatura nacional estudos que estabeleçam parâmetros para a população infantil. Objetivo: Analisar o desempenho de normo-ouvintes, de 8 a 10 anos, nas tarefas de reconhecimento de fala no ruído, por meio do teste HINT. Método: Avaliados 60 escolares, entre 8 e 10 anos, de ambos os gêneros, sem queixas auditivas e escolares, e com resultados dentro da normalidade para a Avaliação Audiológica Básica e o Teste Dicótico de Dígitos. O teste HINT-Brasil foi aplicado com fones de ouvido, sendo pesquisada a relação Fala/Ruído nas condições Ruído Frontal, Ruído à Direita e Ruído à Esquerda. O software calculou o Ruído Composto, que corresponde à média ponderada das condições testadas. Resultados: Não houve diferença estatisticamente significante entre as orelhas, nem entre os gêneros. Houve diferença estatisticamente significante para as faixas de 8 e 10 anos, nas situações com ruído e para o Ruído Composto. A faixa etária de 10 anos apresentou desempenho melhor do que a faixa etária de 8; a faixa etária de 9 anos não apresentou diferença estatisticamente significante com relação as outras faixas etárias. Sugerimos os valores de Média e Desvio Padrão da relação F/R, considerando as faixas: 8 anos - RF: -2,09 (± 1,09); RD: -7,64 (± 1,72); RE: -7,53 (± 2,80); RC: -4,86 (± 1,31); 9 anos - RF: -2,82 (± 0,74); RD: -8,49 (± 2,24); RE: -8,41 (± 1,75); RC: -5,63 (± 1,02); 10 anos - RF: -3,01 (± 0,95); RD: -9,47 (± 1,43); RE: -9,16 (± 1,65); RC: -6,16 (± 0,91). Conclusão: O teste HINT-Brasil é um teste simples e rápido e não oferece dificuldades em seu uso com crianças normo-ouvintes; os resultados mostram se tratar de um teste eficaz para ser utilizado com a faixa etária avaliada.
