Abstract

Subject: Noise influence on speech perception in a group of children with school difficulties. The perception of speech in noise is one of the most complex tasks faced by listeners. This is related the communicative situation in our daily lives often occur in the presence of noise, including the school environment. The high noise in the classroom is frequent and is directly related to academic success. Aim: To analyze the speech perception in noise in children with school difficulties, considering the variables gender, age and ear. Study design: quantitative, transversal and descriptive cohort, children 8 to 10 years old, male and female, and 63 children with school difficulties (GE), according to selection of school teaching staff and 61 students with good academic performance and without hearing complaints and/or language (GC). Material and method: Data collection were applied tests of audiological evaluation basic, the Dichotic Digit Test and Hearing in Noise Test - HINT BRASIL with earphones in a soundproof booth, in silence situation (S), Competitive Noise in Ear right (RD), noise in the left ear (RE) and front noise (RF). Results: The groups were homogeneous for age and heterogeneous group in relation to gender, with more boys in GE and girls in the GC. The information anamnesis revealed that GE¿s children have worse hearing behavior of listening in noisy environments, attention and excitement. The GE had hearing thresholds and LRF worse than the GC, as well as changes auditory peripheral frequently that GC and worst performance in binaural integration task. In speech perception analysis there wasn't intergroup difference for the variables gender and ear side. The age variable influenced the GC. When comparing the performance between the groups it found that GE had worse performance than the CG in front noise condition and compound noise calculation. The RF condition is more difficult for both groups. Conclusion: Children with school difficulties presented a lower peripheral auditory performance, figure background skill for verbal sounds and speech perception in quiet and in noise (AU)
