FIG. 5.

ASR amplitude increased with decreasing LDL. A ASR amplitude at 95 dB SPL (after A-weighting) vs. LDL for the noise stimulus. The ASR was recorded in the noise background condition. Each symbol corresponds to a subject. Filled symbols: tinnitus. Open symbols: no tinnitus. Circles: men. Squares: women. Rightward arrows indicate that the value plotted horizontally is a lower bound on LDL, meaning that the subject did not reach a maximum loudness rating in one or both ears, even at the highest stimulus level used during LDL testing. Regression lines are for all subjects (solid line), for men only (dashed lines), and for women only (dotted lines). Symbols with arrows were not included in the fits. B Same as (A), but for ASR recorded in quiet. C Correlation between ASR amplitude and LDL (for noise and 500-Hz warble stimuli), for both noise and quiet ASR conditions (shaded and white bars, respectively) and ASR stimulus levels from 85 to 110 dB SPL. Correlation coefficients were calculated with the arrowed symbols included. Session 1 data.
