Table 1
Categories of TRT mixing point-level close to the place where the sound from the instrument blends with the tinnitus.
| Category | 0 | I | II | III | IV |
| Tinnitus | Small problem | Serious problem | Serious problem | Present/absent | Present/absent |
| Hyperacusis | Absent | Absent | Absent | Present | Present/absent |
| Noise exposure | No prolonged effect | No prolonged effect | No prolonged effect | No prolonged effect | Prolonged effect |
| Subjective Hl | Absent | Absent | Significant | Irrelevant/ significant | Irrelevant/significant |
| Main problem | Tinnitus | Tinnitus | HL | Hyperacusis | Tinnitus or hyperacusis |
| Treatment | Avoid silence recommendation | Noise generators set at mixing point | Hearing aids with/without noise generators set below mixing point | Noise generator firstly set at hearing threshold then gradually increased to mixing point | Noise generators firstly set at hearing threshold then gradually increased to mixing point |
