FIG. 7.

Lack of correlation between ASR measures and SLTQ. ASR amplitude at 95 dB SPL after A-weighting (A) and ASR threshold (B), both in the noise background condition, plotted vs. SLTQ. Each symbol corresponds to a subject. Filled symbols: tinnitus. Open symbols: no tinnitus. Circles: men. Squares: women. Upward arrows indicate that ASR threshold was higher than the highest ASR stimulus level tested. Downward arrow for the lowest point in (B) (corresponding to subject 378) indicates that ASR threshold was below the lowest ASR stimulus level tested. Regression lines are for all subjects (solid), men only (dashed), and women only (dotted) and were fit with the arrowed symbols excluded. C Correlation coefficients between SLTQ and ASR amplitude were small and not significant (|r|(37–50) ≤ 0.088, p ≥ 0.29) at any stimulus level, in both noise and quiet ASR measurement conditions (gray and white bars, respectively).
