Figure 3: Mean (standard error of mean [SEM], n = 13) data for tinnitus subjects (3 frequencies, 1octave below, 1octave above and at the tinnitus frequency) and notinnitus subjects (3 frequencies, 1.2, 8 and 12.6 kHz) for the left ear (a) and right ear (b). Mean scores of tinnitus subjects were significantly less (P < 0.01) than notinnitus subjects in the left ear. Scatterplot showing the percent correct detection of 50 ms gaps versus dB HL in the left ear (c) and right ear (d) of tinnitus subjects. Data and linear regression lines are shown for frequencies 1octave below, 1octave above and at the tinnitus frequency. Significant values for the regression analysis are shown in the legend of each panel
