Individual (top panel) and mean (bottom panel) masked-SAM detection sensitivity. Thresholds at these supra-threshold masker depths increased at a rate of about 1 dB (20 log m) per 1 dB (masker rms); the dashed lines in the two panels serve as a reference with a 1 dB/dB slope. Signal fm=64 Hz; masker bandwidth=32 Hz, centered on signal frequency; SPL=65 dB; carrier fc=2800 Hz; duration=600 ms. Standard deviations of individual listener threshold estimates were between 2 and 4 dB (error bars omitted for clarity).
