SUMMARY:

Introduction: The Frequency Following Response (FFR) is an auditory evoked potential that non-invasively evaluates the neural decoding of speech. Objectives: Study 1: to study FFR responses with speech stimuli in the frequency and time domain in typical infants, children and adults according to age and evaluated ear. Study 2: to analyze the development of the auditory pathway using the Frequency Following Response with speech stimulus in babies with congenital syphilis treated during the first two years of life. Method: Cross-sectional study, approved by the Research Ethics Committee nº 5,685,328. FFR performed with the speech stimulus /da/ synthesized with a fundamental frequency of 100 Hz, duration of 170 ms, speed of 3.70/s. The first 10 ms of onset, 47 ms of consonant-vowel transition and 113 ms of vowel sustain. Four averaging of 1,000 sweeps were presented, analysis window from -40 to 270.27 ms at 80dBnHL on the SmartEP platform. Artifacts below 10% and online bandpass filter of 30-3000 Hz. Descriptive and inferential analysis was applied in both studies according to the distribution of data and variables, adopting a significance level of 5%. Partial results: Study 1: sample consisting of 14 babies aged up to 60 days, 13 babies aged 24 months and 36 adults between 19 and 46 years old, 27 females and nine males. Partial results suggestive of difference between ages in the parameters: Spectral amplitude of F0 and Neural lag, in addition to better right ear response in subjects aged 24 months Study 2: sample consisted of 89 babies with congenital syphilis and 63 control babies. Partial results point to no difference in the comparison between the groups in terms of frequency and time, but there are indications that intra-groups have an influence of age in the group of babies with congenital syphilis throughout development or that it was observed in smaller numbers of parameters in the control group throughout development.
