Design outcomes

Primary

Measure	Time frame
Tinnitus questionnaires TQ52 (Goebel and Hiller). We evaluated the TQ52 scores for six months post-intervention period. TQs were evaluated after three and six months respectively	—

Secondary

Measure	Time frame
Evaluation of electroencephalographic data (wavelet phase stability as habituation measure). We utilized ramped pure tone bursts (40ms) in the individual tinnitus frequency at MCL. Evaluation of 600 single sweeps	—
