The aim of this study is to analyze the relationship between age and the maturational changes occurring in the peripherical auditory system and the influence of the acoustic stimulation. With this purpose Auditory Brainstem Responses (ABR) were recorded at the 35 and 39 weeks gestational age, in 56 ears of 28 premature infants. The ABR were analyzed the changes in latency values of the I, V waves and I-V intervals. In order to know the influence of the acoustic stimulation on the development of auditory pathway, we made 2 groups with the 28 premature children, one of them control group and the other stimulated with maternal voice from 35 till 39 weeks. The stimulated group had one maturate auditory evoked responses at 39 weeks gestational age. Showing a latency decrease wave V and I-V interval, compared to control group. |
