Fifty-dB sound pressure level (SPL) auditory steady-state response (ASSR) detection with magnitude-squared coherence (MSC). Individual #3 window detection: 50-dB SPL record. The MSC values after 150 sweeps are shown vertically. Horizontal Line: critical MSC (critical value to consider frequency presence). Bars: left ear (LE) and right ear (RE) modulations. The black star points indicate the frequencies with superior critical values after 150 sweeps of false positive detections.
