Mean hearing threshold (in dB HL): average of all thresholds measured bilaterally ranging from 125 Hz to 8 kHz. Tinnitus laterality is defined in categories: r, right-sided; l, left-sided, l > r, both sides but louder on the left side; r > l, both sides but louder on the right side; both, both sides; inside head, tinnitus is perceived in the middle of/ inside the head. TQ, Tinnitus Questionnaire; THI, Tinnitus Handicap Inventory; MDI, Major Depression Inventory; rating scales ranging from 0 (not at all loud/uncomfortable etc.) to 10 (extremely loud/uncomfortable etc.); WHO-QoL, World Health Organization-Quality of Life; NPAD, neck pain and disability scale.
