Relative level of the output of the dcGC for a 1000-Hz probe tone, as a function of suppressor level, when the suppressor frequency is either 400 Hz (left panel) or 1400 Hz (right panel). The numbers in the left-hand side show the probe level in decibels SPL. The output level is normalized to 50-dB SPL by shifting a constant decibel value. There is suppression whenever the probe level drops below its starting value where the suppressor is 20-dB SPL.
