Correlation of band power averaged over all electrodes with audiological and psychological parameters of the patient group.

Correlation coefficients (Spearman's ) and corresponding significance levels () between tinnitus characteristics, minimum masking level (MML), mean hearing loss (MHL), tinnitus-related distress (TinDis), psychometric testing scores and oscillatory band power in the delta to gamma range are reported for the whole tinnitus group. MHL: mean hearing loss averaged for left and right ears between 0.125 kHz and 16 kHz; TL: tinnitus loudness measures (see section “Psychoacoustic measurements” and Table 2); MML: minimum masking level with white noise; : minimum masking level with white noise above mean hearing threshold; TinDur: tinnitus duration in years; TinDis: tinnitus-related distress; DEP: depression subscale of the SCL-90-R; SOM: somatization subscale of the SCL-90-R; ANX: anxiety subscale of the SCL-90-R. Significant correlations () are indicated by bold letters. Correlations which remained significant after FDR correction (FDR 0.05) are denoted by at the corresponding -value.
