Abstract
PURPOSES AND METHODS: The aims of this study were: to detect moderate to profound hearing loss in high risk infants for deafness, to follow up their auditory development (localization of the sound source- Hear Kit - Downs, 1984); and their neuropsychomotor development during the two first years of life. All subjects were submitted to cerebral ultra sound assessment. An infant with a suspected hearing loss was identified and nine infants presented neuropsychomotor development delay. In a transversal analysis of the hearing assessment data it was verified that infants in this study presented different response than the referred in the American literature. It was concluded that 5% of the infants were delayed in localizing the sound source. Medical peech and hearing follow up during the two first years of life of high risk infants for deafness is important and advisable.

Estudo e avaliação do comportamento auditivo de recém-nascidos normais e de alto-risco - Estudo preliminar
Summary
Para estudar o nível de maturação deste sistema no período neonatal durante os 23 meses seguintes, pesquisadores recorrem aos testes de percepção auditiva, como por exemplo, de discriminação dos sons da fala[1,2] e da localização da fonte sonora[3,4,5,6]. Os objetivos deste estudo foram detectar a presença de deficiência auditiva (DA) de moderada a profunda em lactentes de baixo peso ao nascimento, e na ausência desta, acompanhar o desenvolvimento da função auditiva (localização da fonte sonora), e acompanhar o desenvolvimento neuropsicomotor destas crianças durante os dois primeiros anos de vida.
