This study evaluates the treatment efficacy of tinnitus in people with mild hearing loss. One-third of participants will use hearing aid, one-third of participants will use customized music, while the other one-third participants will receive no treatment (waiting list control).
Acoustic stimulation could induce plastic changes in the auditory cortex, and tinnitus mechanisms have been viewed as a negative consequence of neural plasticity in the central nervous system after peripheral aggression. Cortical changes (neural activity in the deafferented cortical area was reduced but the adjacent frequencies of the hearing loss region activated more extensive cortical areas) occur after sensorineural hearing loss, while exposure to an acoustically enriched environment or using hearing aids may minimize or reverse the plastic tonotopic map changes in the auditory cortex. The use of hearing aids in tinnitus management for people with significant hearing loss will always be associated with an improvement in hearing handicap and quality of life, and that complicates the interpretation of how much hearing aids specifically affect tinnitus. Thus studies on tinnitus patients with mild hearing loss could be illuminating, and this population will be targeted in the present study.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Waiting list control group | No Intervention | There will be no treatment for 12 months. | |
| Hearing aid group | Experimental | Participants will receive amplification with hearing aids. Bilateral open-fit hearing aids will be fitted. Participants will be required to use the hearing aids for at least 2 hours daily for 12 months. |
|
| Customized music group | Active Comparator | Customized music according to participants hearing level will be made available in an iPod. The iPod will deliver ear-specific therapeutic sound for asymmetrical hearing profile. Participants will have to listen to the therapeutic sound at a comfortable volume for two hours daily for 12 months. |

| The Tinnitus Functional Index (Chinese version) (TFI-CH) | TFI-CH is a 25-item self-administered questionnaire which assesses eight domains of tinnitus impact: intrusiveness; sense of control; cognitive; sleep; auditory; relaxation; quality of life (QoL); emotion. The total TFI score ranges 0 - 100, the higher score is indicative of greater problem with tinnitus. | Change from baseline value at 3 months, 6 months and 12 months after the first day of treatment will be measured. |

| The Tinnitus Questionnaire (Chinese version) (TQ-CH) scores | The TQ-CH is a 52-item questionnaire which assesses five dimensions of tinnitus complaint: emotional distress; auditory perceptual difficulties; intrusiveness; sleep disturbance; and somatic complaints. The total TQ score ranges 0 - 104, the higher score is indicative of greater problem with tinnitus. | Change from baseline value at 3 months, 6 months and 12 months after the first day of treatment will be measured. |

| The Tinnitus Handicap Inventory (Chinese version) (THI-CH) scores | The THI-CH is a reliable 25-item self-administered Chinese QoL tool that quantifies the impact of tinnitus on daily living. The total THI score ranges 0 - 100, the higher score is indicative of greater tinnitus handicap. | Change from baseline value at 3 months, 6 months and 12 months after the first day of treatment will be measured. |
| Self-rated Visual Analogue Scale (VAS) on tinnitus loudness | The subjects will be asked to rate the perceived loudness of their tinnitus on VAS, with "inaudible" (scale rating value = 0) and "very loud" (scale rating value = 100) as reference points for the ends of the scale. The higher rating is indicative of louder tinnitus. | Change from baseline value at 3 months, 6 months and 12 months after the first day of treatment will be measured. |
| Tinnitus loudness matches at the tinnitus frequency and at 1000 Hz | Tinnitus loudness matches will be done according to Vernon and Meikle's procedure | Change from baseline values at 3 months, 6 months and 12 months after the first day of treatment will be measured. |
| The Chinese Hospital Anxiety and Depression Scale (HADS) | The Chinese HADS is a 14-item questionnaire that consists of two subscales that measure anxiety and depression. It serves as an outcome measure targeting psychological and mental health effects. | Change from baseline value at 3 months, 6 months and 12 months after the first day of treatment will be measured. |
