The effect of noise on the amplitude and morphology of cortical auditory evoked potentials

Abstract Objective: To analyze the effect of noise on electrophysiological measurements (P1-N1-P2 complex) of cortical auditory evoked potentials in normal hearing individuals of different ages. Methods: The inclusion criteria for the study were young individuals, adults and elderly, aged 18–75 years, with auditory thresholds up to 25 dB. Participants were separated according to their age group: G1 (18–25 years old), G2 (31–59 years old) and G3 (60–75 years old). Cortical auditory evoked potentials were elicited with synthetic speech stimulus /da/ presented in two conditions: without...
