Design outcomes
Primary
| Measure | Time frame |
|---|---|
| (this text is taken from the protocol) The primary study variable is the intensity of the experienced tinnitus and is measured using Visual Analogue Scales. VAS will be used because it is a quick measurement which is often used in comparable studies. | — |
Secondary
| Measure | Time frame |
|---|---|
| (this text is taken from the protocol) Because tinnitus is a subjective phenomenon, its intensity and impact are further identified by means of questionnaires (Tinnitus Questionnaire and Tinnitus Handicap Inventory) and audiological tests (Tinnitus Loudness Matching and Residual Inhibition) which have a more objective character. These secondary endpoints will give additional information which is desirable because of the subjectivity of this phenomenon and provides more certainty. | — |
