Data replotted from Humes (1990) for detection of 4.6-msec probe tones in the peaks (filled symbols) and troughs (unfilled symbols) of 100% amplitude-modulated noise. Results at 500 Hz are plotted in the top panel, at 1400 Hz in the middle panel, and at 4000 Hz in the bottom panel. In each panel, masked threshold in dB SPL is plotted as a function of modulation frequency for each of three groups of listeners: NH listeners (circles), HI listeners (diamonds), and noise-masked NH listeners (squares). [Note that circles and squares overlie each other in top panel.]
