Group means and standard deviations are reported. Auditory measures: mean hearing loss (MHL, left and right ear averaged for the frequency range 0.125 kHz to 16 kHz); mean threshold of uncomfortable loudness (UCL, left and right ear averaged for the frequency range 0.125 kHz to 10 kHz). Psychological measures derived from the SCL-90-R: global severity index (GSI), positive symptom total (PST), positive symptom distress index (PSDI), depressiveness subscale (DEP), somatization subscale (SOM), anxiety subscale (ANX). Tinnitus characteristics: tinnitus duration (TinDur), tinnitus-related distress (TinDis) derived from the Tinnitus Questionnaire (scores 
: low tinnitus-related distress, scores 
: high tinnitus-related distress). Tinnitus loudness measures (TL, see section “Psychoacoustic measurements” and Table 2); frequency of the major peak in tinnitus spectrum (
); minimum masking level when masking with white noise (MML) as well as minimum masking level above mean hearing threshold (
); rating of similarity of reconstructed tinnitus sound to own tinnitus (RTS, 0: no match, 10: perfect match).
