RESUMO

INTRODUCTION: One of the main implications of hearing impairment is the difficulty in perceiving speech sounds, especially in noisy environments. Thus, the frequency-modulated system is considered an important educational tool for children with hearing impairment because it improves speech perception in acoustically-unfavorable environments, such as in the classroom. The assessment of speech perception in noise is included in the verification protocol of this device. OBJECTIVES: To verify the effectiveness of the phrases in noise test Brazil in children with hearing impairment using an frequency-modulated system. METHODS: This was a cross-sectional cohort study. The sample included 40 children, aged 4 years to 11 years and 11 months old, divided into 4 groups: (1) 10 normal hearing children; (2) 13 children with hearing aids and frequency-modulated system; (3) 12 children using cochlear implant and fitted with the frequency-modulated system; and (4) 5 children diagnosed with auditory neuropathy spectrum disorder, fitted with hearing aids and/or cochlear implant and with the frequency-modulated system. The phrases in noise test Brazil was used to evaluate speech perception in noise under the conditions with and without the frequency-modulated system. For the statistical analysis of the data, a significance level of 5% (p < 0.05) was adopted. RESULTS: There was a significant difference between the groups when they were evaluated with the frequency-modulated system. The test was also validated through concurrent and convergent validation measures. Phrases in noise test Brazil is a viable option for monitoring auditory performance in noise in different groups of children with hearing impairmen. CONCLUSION: Phrases in noise test Brazil was effective in assessing speech perception in noise and may contribute to the improvement of the indication, fitting and follow-up protocols for the frequency-modulated system use.

RESUMO

PURPOSE: To determine nasalance scores of Brazilian Portuguese speaking children without evident speech disorders, language delay and orofacial deformities, at age 5 years, and analyze differences between types of speech samples and genders. METHODS: Twenty children were analyzed, 11 males, age ranging from 4 years and 10 months to 5 years and 11 months. The Nasometer II 6450 (KayPENTAX) was used for nasalance assessment. Speech samples were eight consonant-vowel syllables and one sequence of nine words. The significance of differences between speech samples and genders were assessed by the Tukey test and Mann-Whitney test, respectively, at a significance level of 5%. RESULTS: Mean nasalance scores were: /pa/= 10±4%, /pi/= 22±7%, /sa/= 11±5%, /si/= 24±11%, /ma/= 57±11%, /mi/= 73±13%, /la/= 14±9%, /li/= 25±11%, words (pipa, bis, burro, tatu, pilha, cuca, gui, fila, luz)= 20±6%. Nasalance scores of nasal syllables were significantly higher than those of oral syllables (with high or neutral vowels) and nasalance scores of oral syllables with high vowels were significantly higher than those of oral syllables with neutral vowels, for the majority of comparisons. There was no difference between genders. CONCLUSION: Normative nasalance scores for 5-year-old Brazilian children were determined. The methodology can serve as a standard for the early diagnosis of nasality deviations, such as hypernasality observed in cleft palate speech.

RESUMO

RESUMO Objetivo Determinar valores de nasalância de crianças falantes do Português Brasileiro sem alterações na produção da fala, atraso de linguagem e deformidades dentofaciais evidentes, aos 5 anos de idade, e verificar as diferenças entre tipos de emissão e entre gêneros. Método A nasalância foi determinada em 20 crianças, 11 do gênero masculino e idade entre 4 anos e 10 meses e 5 anos e 11 meses, utilizando um nasômetro II 6450 (KayPENTAX), na produção de oito sílabas tipo consoante-vogal e uma sequência de nove vocábulos. A significância das diferenças entre os tipos de emissões foi verificada pelo Teste de Tukey e, entre os gêneros, pelo teste de Mann-Whitney, para um nível de 5%. Resultados Os valores médios de nasalância foram os seguintes: /pa/= 10±4%, /pi/= 22±7%, /sa/= 11±5%, /si/= 24±11%, /ma/= 57±11%, /mi/= 73±13%, /la/= 14±9%, /li/= 25±11%, vocábulos (pipa, bis, burro, tatu, pilha, cuca, gui, fila, luz)= 20±6%. Na maioria das comparações, os valores de nasalância das sílabas nasais foram significantemente maiores do que os das sílabas orais (com vogal alta ou neutra) e os valores das sílabas orais com vogal alta foram significativamente maiores que os das sílabas orais com vogal neutra. Não houve diferença significante entre os gêneros. Conclusão Foram definidos valores normais de nasalância de crianças falantes do Português Brasileiro, de 5 anos de idade, sendo que a metodologia empregada pode servir de padrão para o diagnóstico precoce de desvios de nasalidade, como a hipernasalidade observada na fala de crianças com fissura palatina.
