Abstract

In this paper, we present the performance analysis of four statistical detection tests for the Auditory Steady-State Response (ASSR): F test, phase coherence (PC), magnitude-squared coherence (MSC) and T 2 circular (T2). The detector’s accuracy levels were analyzed by the receiver operating characteristic method. The ASSR was modeled by a sinusoidal response and a noise component generated by the Burg method. The MSC and T2 tests presented slightly better performances than the others, however the difference was not enough to consider the impact of the choice of the statistical detection method in the levels of accuracy as significant.
