Summary

Introduction: The ability to understand speech is impaired by many factors during evaluations, especially under noise, and it is still more complex for children under these conditions.

Objective: To analyze the speech perception in children with a normal hearing in different noise situations.

Method: Way of study transverse section. The Brazilian Hearing in Noise Test (HINT) was performed in 21 children aged between 7 and 14 with a standard hearing and no cognitive alterations. The sentence lists were randomly used in these situations: silence (S), frontal noise (FN); right-side noise (RN); left-side noise (LN); noise at 180°. (RT) and a comparison between the result of the compound noise (CN) and the diffuse noise in four sound areas at 45°; 135°; 225° e 315° (4 BXS).

Results: The statistical analysis showed a significant difference among the following situations: RN with FN; BN with FN; and it was worse with 4 BXS, where a difference for RN, BN, CN, LN and FN was found. To analyze a correlation with age, it was significant regarding the age, as a result of HINT values only for the frontal noise.

Conclusion: The significant differences in the results of speech perception among the different hearing conditions in the evaluated individuals suggest carefulness when choosing the stimulus in evaluations of speech perception in the noise in hearing-impaired children. Accordingly, researches in this field are necessary to determine the standards and variations related to its application and result interpretation.

Resumo

Introdução: A habilidade em compreender a fala é afetada por muitos fatores durante as avaliações, principalmente no ruído, sendo ainda mais complexa para crianças nessas condições.

Objetivo: Analisar a percepção da fala em crianças com audição normal em diferentes situações de ruído.

Método: Forma de estudo corte transversal. Foi utilizado o Brazilian Hearing in Noise Test (HINT) em 21 crianças de sete a 14 anos com audição dentro dos padrões de normalidade, e sem alterações cognitivas. Foram aplicadas, aleatoriamente, as listas de sentenças nas seguintes situações: silêncio (S); ruído de frente (RF); ruído à direita (RD); ruído à esquerda (RE); ruído a 180°. (RT) e comparado o resultado de ruído composto (RC) com ruído difuso a partir de quatro campos de som em 45°; 135°; 225° e 315° (4CXS).

Resultados: A análise estatística revelou diferença significativa entre as seguintes situações: RD com RF; RT com RF; sendo pior com 4CXS, onde foi encontrada diferença para RD, RT, RC, RE e RF. Para a análise de correlação com a idade, houve significância entre a idade em função dos valores HINT apenas para o ruído à frente.

Conclusão: As diferenças significativas nos resultados de percepção da fala entre as diferentes condições de escuta no ruído na população estudada sugerem cautela na escolha do estímulo em avaliações de percepção da fala no ruído em crianças deficientes auditivas. Assim, pesquisas nessa linha são necessárias para estabelecer os parâmetros e variáveis relacionadas à sua aplicação e a interpretação dos resultados.
