Fig. 6From: Human detection thresholds of DC, AC, and hybrid electric fields: a double-blind studyHistograms of SIAM detection thresholds: For a DC EF, b AC EF, and c hybrid EF. In hybrid sessions, various DC EFs (x-axis) were always combined with an AC EF of 4 kV/m. White bars at the left and right edges reflect the participants with min or max termination criteria, where no detection threshold could be assessedBack to article page
