【 摘 要 】

Multiple auditory steady state responses (MASSR) is used to assess the integrity auditory pathways for different frequencies applied simultaneously without significant increases in exam time. Objective Response Detection (ORD) techniques have been employed for hearing screening since it conducts to response identification with statistical basis. This work aims at comparing time and detection rate of two ORD, Rice detector (RD) and Component Synchrony Measure (CSM). The binaural auditory stimulation was applied to 21 normal hearing infants and consisted of four amplitude-modulated (AM) tones presented simultaneously on each ear with the carriers 500, 1000, 2000 and 4000 Hz, and at 50 and 40 dB SPL intensity levels. The CSM presented higher detection rates than RD for all carriers, both intensities and ears (statistical difference, assessed by proportion test with significance level of alfa=0.05, only for 500 Hz in both ears and for 1000 Hz in the left ear). Moreover, detection times were lower for CSM compared to RD (unpaired Wilcoxon rank-sum test with alfa=0.05 indicated statistical difference for 1000 Hz at 50 dBSPL and 2000 Hz at 50 dBSPL both for the left ear). Hence, the CSM could be considered more effective for hearing screening purposes.
