Hearing Loss, High-Frequency, Tinnitus, Subjective
Conditions
Brief summary
Considering the extent to which HAs play a role in sound perception and residual hearing preservation among patients with tinnitus and co-existing HL remains a lack of compelling extensive evidence, investigators designed this single-blind, 6-months randomized, controlled trial with two parallel groups. One is the HA treatment group, and the other is the waiting list control (WLC) group which receives no interventions during this period.
Detailed description
In clinical practice, chronic subject tinnitus poses an important challenge. This condition can negatively affect an individual's emotional and functional well-being. In most cases, tinnitus is highly associated with hearing impairment, particularly in cases of high-frequency sensorineural hearing loss (SNHL). The occurrence of tinnitus in patients with HL is one of the most prevalent sensory disabilities, causing a deleterious effect on patients' lives. Nowadays, the mild to moderate SNHL can be effectively managed with a fitting hearing aid (HA) by providing sound amplification, and several findings suggest that the HA may also be helpful for people with tinnitus. Nevertheless, in terms of the effects of HA use for residual hearing protection for patients with tinnitus and co-existing hearing loss, inadequate attention is still paid by medical personnel, and relevant evidence remains preliminary at this point in time. To assess the full extent of tinnitus patients, investigators need to carry out a series of tests, including hearing assessment and psychometric tests. Pure tone audiometry (PTA) and otoacoustic emission (OAE) tests are used to calculate the average hearing thresholds and the outer hair cell function, while the Tinnitus hazard Index (THI), the Visual Analogue Scale (VAS), the Hospital Anxiety and the Depression Scale (HADs) and the Athens Insomnia Scale-8 (AIS-8) questionnaires were for patients' psychology status. Investigators hypothesize that in patients with tinnitus and hearing loss, HA intervention results in better conditions of tinnitus and lower hearing threshold reduction. Here investigators planned to enroll patients into two groups, the HA and non-HA (served as the control) intervention patients.
Interventions
DEVICEHearing aids
As for screening the hearing and tinnitus testing, the measure typically comprises PTA, SRS, DPOAE, and several widely accepted standardized tinnitus questionnaires, including the THI for tinnitus severity and VAS for tinnitus loudness.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| tinnitus handicap inventory (THI) | 3 months from baseline | The THI is a self-administered test, including 25 questions with grades four categories of tinnitus severity: slight corresponding to a score of 0-16, mild (18-36), moderate (38-56), severe (58-100). The higher the score the more severe the tinnitus. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| speech recognition score (SRS) test | 3 months from baseline | The list consists of 25 monosyllabic words, and each word is rated on a 4-point scale with a total score of 100. A higher score indicates a better level of auditory comprehension and speech recognition. |
| pure tone audiometry (PTA) | 3 months from baseline | PTA is performed to calculate the average hearing thresholds obtained at multiple frequencies in dB hearing level. |
| otoacoustic emission (OAE) | 3 months from baseline | OAE test could help evaluate the mechanism of tinnitus since it determines whether or not the outer hair cells are overexcited or damaged. |
| the Hospital Anxiety and Depression Scale (HADs) | 3 months from baseline | The HADs consist of 14 items which are equally divided into two dimensions: a depression sub-scale (HADs-D) and an anxiety sub-scale (HADs-A). The grades are valued by scoring: negative (0-7), positive (8-21). |
| the Athens Insomnia Scale-8 (AIS-8) | 3 months from baseline | The AIS comprises eight items that commonly measure difficulties in falling asleep or maintaining sleep to quantify the presence of insomnia. The higher the AIS score, the lower the sleep quality and mental status. The AIS identifies three types of sleep disorders: no insomnia (score below 4), suspicious (4-6), and insomnia (score between 7-24). |
