ABSTRACT
Purpose: To evaluate the stability of parameters of auditory evoked potentials in normal adults. Methods: Forty-nine normal subjects with ages from 18 to 40 years (25 females and 24 males) were submitted to audiological and electrophysiological hearing evaluation (auditory brainstem response - ABR, middle latency response - MLR, and cognitive potential - P300). Subjects were reassessed three months after the initial evaluation. Results: Significant differences were observed between genders regarding the wave latencies III and V and the interpeaks I-III and I-IV of ABR, and the amplitude N2-P3 of the P300. No differences were found between the results of initial and final assessments for the parameters of the ABR, MLR (Na, Pa latencies and Na-Pa amplitude) and P300 (P300 latency). Conclusion: Except for the N2-P3 amplitude, it was observed stability of the parameters of ABR, MLR and P300 in normal adults after a period of three months.
