Speech perception in children in noisy situation

INTRODUCTION: The ability to understand a speech is affected for several factors during the evaluation mainly noise, and being more complex for children in these conditions. OBJECTIVE: To analyse the speech perception in children with normal hearing in different situations of noise. METHOD: Study's way transversal cut. It was used the Brazilian Hearing in Noise Test(HINT) in 21 children with 7-14 years old with hearing inside the normality patterns and without cognitive alterations. Randomly was applied, sentence lists in the following situations: silent (S), noise in front (FN), noise at right (RN), noise at left (LN) noise at 180º(TN) and compared the result of compound noise (CN) with diffuse noise from 4 sound fields in 45º, 135º, 225ºand 315º(4CXS). RESULTS: The statistics analyse showed the following situations: RH with FN; TN with FN; being worse with 4CXS, where was found difference for RN, TN, CN, LN and FN. To annalyse the age correlation, there was significance between age in HINT value functions just for noise in front. CONCLUSION: The significative differences in the speech perception results among the different conditions of hearing in noise in the studied population suggest caution in choosing the stimulus in speech perception evaluation in noise in auditive deficiency children. So, researches in this line are necessary to establish the parameters and variables related to their application and results interpretation.
