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.
